Bug report: parse_coins not handling factory tokens

[joaophi]

Prerequisites

• I am running the latest CosmPy version.
• I checked the documentation and found no answer to my problem.
• I checked the existing issues to make sure my problem has not already been reported.
• I have read the code of conduct before creating this issue.

Expected Behavior

Allow to execute contract with factory tokens funds like 33362484factory/kujira1r85reqy6h0lu02vyz0hnzhv5whsns55gdt4w0d7ft87utzk7u0wqr4ssll/uusk

Current Behavior

the parse_coins function is only picking the 33362484 and factory resulting in a failed to execute message; message index: 0: 0factory is smaller than 33362484factory: insufficient funds

root cause:

cosmpy/cosmpy/aerial/coins.py

Line 43 in cb4bc0a

match = re.match(r"(\d+)(\w+)", part)

suggestion:

match = re.match(r"(\d+)([\w/]+)", part) 

To Reproduce

wallet = LocalWallet(private_key, prefix="kujira")

cfg = NetworkConfig(
    chain_id="harpoon-4",
    url="rest+https://lcd.harpoon.kujira.setten.io",
    fee_minimum_gas_price=0.025,
    fee_denomination="ukuji",
    staking_denomination="ukuji",
)
ledger_client = LedgerClient(cfg)

contract = LedgerContract(path=None, client=ledger_client, address=Address(
    "kujira1exd7mzv8azf7tpqukm6fzxnvdt7a8kddyz2puwzk9lm7qmlx3vxq0thezm"))

def submit_bid(premium_slot: int, funds: str) -> SubmittedTx:
    message = {"submit_bid": {"premium_slot": premium_slot}}
    tx = contract.execute(message, wallet, gas_limit=237153, funds=funds)
    return tx.wait_to_complete()


result = submit_bid(premium_slot=30, funds="33362484factory/kujira1r85reqy6h0lu02vyz0hnzhv5whsns55gdt4w0d7ft87utzk7u0wqr4ssll/uusk")
