feat: add parameter context to errors

[2wheeh]

Description

When ABI encoding fails, the error contains no information about which parameter caused the failure.

This makes it difficult to programmatic error handling. Ex, mapping errors to specific form fields.

Changes

• adds parameter: AbiParameter field to encoding-related error classes.

Usage

Form Integration

function parseEncodingError(error: unknown) {
  if (error instanceof Address.InvalidAddressError && error.parameter) {
    return {
      field: error.parameter.name,
      message: `${error.parameter.name} must be a valid address`,
    }
  }
  if (error instanceof Hex.IntegerOutOfRangeError && error.parameter) {
    return {
      field: error.parameter.name,
      message: `${error.parameter.name} is out of range`,
    }
  }
  // ... 
}
