Load dynamic arrays from calldata

[clearloop]

Describe the feature

case 1 - dynamic array as the only param

pub fn foo(dyn_array: String) {
  // ...
}

case 2 - dynamic array after types

pub fn foo(num: i32, dyn_array: String) {
  // ...
}

case 3 - dynamic array in the middle of params

pub fn foo(num: i32, dyn_array: String, boolean: bool) {
  // ...
}

Solution

1. align calldata to the solidity ABI spec
2. detect dynamic arrays in parameters from function signature
3. when local.get happens on dynamic arrays, use chained instructions to extract them
