Upgrading and cleaning up basic_bitcoin example

[kristoferlund]

Summary:

• Add support for Segwit
• Upgraded all dependencies to late(st) versions
• Align naming more clearly with standard terminology
• Simplify the structure, let functionality hidden in functions within functions bubble up to the service function level. When we share one of these examples with a dev, they should be able to get the full picture without havuing to click down 2-3 levels into subfunctions.
• Use BIP-32 path derivation instead of custom

256c45b5230b — Upgrading dependencies, cleaning up, first take

• Remove custom build script as it is not needed
• Remove rust-toolchain settings, not needed for demo purposes
• Adding default settings for running bitcoind from project folder
• Replace custom canister type with rust type to allow for standard dfx deploy
• Upgrading ic_cdk to v18 and as a consequence, changed a lot of management canister call signatures etc

49bbff34e947 — Upgrade to ic_cdk 18

• Upgrade bitcoin dependency to 0.32.5
• Remove bitcoin_api.rs as it just wraps the default bitcoin canister calls -
  introduces abstraction without purpose

92b72a36ea80 — Use management canister api calls instead of "raw" unbounded calls.

• ic_cdk::call::Call::unbounded_wait(super::mgmt_canister_id(), "sign_with_ecdsa") becomes management_canister::sign_with_ecdsa, etc
• Replace local schnorr types with the ones defined in ic_cdk

6176865f842e — Rename to align with management canister naming

bac595d71d81 — Storing a global, empty derivation path serves no purpose.

a2f1f45b50ef — "key_name" is a function of network and should not be stored separately

• Avoid duplication

dab7b45b4de8 — Simplify ecdsa_public_key

• Cleanup for better readability

0b8917bfce2e — Refactor, remove unnecessary subfolder

• Simplify naming and imports
• Remove bitcoin_wallet as it serves no clear purpose. The whole project is about bitcoin wallets.

2744f5d21997 — Cache Schnorr pubkeys

• Just like the ECDSA keys. Schnorr don't like to be left out.

ff79ff6aa5ad — Add support for Segwit address creation

• Almost the only addition in this PR.

8cd2bc50aae1 — Refactor: Create individual service functions for better readability and integration with dev docs

• One service function in each file makes the project easier to navigate. Also makes it easier to reference these service functions in dev docs elsewhere.
• Also, introduced the concept of BitcoinContext, a struct that is initialised on init and upgrade and can be passed around.

pub struct BitcoinContext {
    network: Network,
    bitcoin_network: bitcoin::Network,
    key_name: &'static str,
}

533be3ff9e18 — Refactor: Naming, comments

c94d23aa0774 — Add support for p2wpkh sending

• The other half of Segwit support - sending BTC from a Segwit address.

1b841d12aca1 — Refactor: Remove manual sec1_to_der fn, etc

• Signature provides the built in signature.serialize_der()

c826f4d9d682 — Adding a BIP-32 standard derivation path implementation

Instead of using this very custom derivation scheme:

const P2PKH_DERIVATION_PATH_PREFIX: &str = "p2pkh";
const P2WPKH_DERIVATION_PATH_PREFIX: &str = "p2wpkh";
const P2TR_DERIVATION_PATH_PREFIX: &str = "p2tr_key_and_script_path";
const P2TR_KEY_ONLY_DERIVATION_PATH_PREFIX: &str = "p2tr_key_path_only";

... use standard, BIP-32 derivation paths instead.

• Align better with standard terminology
• More comments

@dfinity/execution, this one should be good to go unless you have comments
