Improve encoder for Vector<bytes> to support uInt8Array

[cold-briu]

Motivation

As seen in this forum topic, the encoder for Vector expects a regular array and will throw an error when being used with uInt8Array.

This requires the user to manually transform the uInt8Array into a common array.

One thing that we can do when trying to encode Vector of bytes or any similar type that will also applied to this, is to validate if it's a UInt8Array and then transform it to regular Array. But we need to validate this approach first.

Usage example

// current
const hexStrArr = ['0x123, 0xABC', ...]
const parsedData = hexStrArr.map((v) => Array.from(arrayify(v)))
await contract.functions.my_fn(parsedData)

// expected
const hexStrArr = ['0x123, 0xABC', ...]
const parsedData = hexStrArr.map((v) => arrayify(v))
await contract.functions.my_fn(parsedData)

Possible implementations

IDK, but it would be here

export class VectorType extends ArrayType {
  public static swayType = 'struct Vec';

  public name = 'vector';

  static MATCH_REGEX: RegExp = /^struct Vec/m;
  static IGNORE_REGEX: RegExp = /^struct RawVec$/m;

  static isSuitableFor(params: { type: string }) {
    const isAMatch = VectorType.MATCH_REGEX.test(params.type);
    const shouldBeIgnored = VectorType.IGNORE_REGEX.test(params.type);
    return isAMatch && !shouldBeIgnored;
  }

  public parseComponentsAttributes(_params: { types: IType[] }) {
    this.attributes = {
      inputLabel: `Vec`,
      outputLabel: `Vec`,
    };
    return this.attributes;
  }
}

@danielbate Will this still be relevant, or should it be closed in favor of #1672?
