typia.protobuf.decode ignored byteOffset and byteLength

[ghlin]

Calling typia.protobuf.decode (or typia.protobuf.createDecode) with Buffer throws 'buffer overflow'.

minimal code to reproduce:

import typia from 'typia'

type Foo = {
  id: number & typia.tags.Type<'int64'>
}

const decode = typia.protobuf.createDecode<Foo>()

const obj = { id: 12 }
const encoded = typia.protobuf.encode<Foo>(obj)

try {
  const buffer1 = Buffer.from(encoded)
  const decoded1 = decode(buffer1) // throws

  console.log(obj, decoded1)
} catch (e) {
  console.error(e) // Error on typia.protobuf.decode(): buffer overflow
}

// while this works fine.
const buffer2 = Buffer.from(encoded.buffer, encoded.byteOffset, encoded.byteLength)
const decoded2 = decode(buffer2)

console.log(obj, decoded2) // { id: 12 }, { id: 12 }

I tried to patch the constructor code in $ProtobufReader to:

  public constructor(buf: Uint8Array) {
    this.buf = buf;
    this.ptr = 0;
    this.view = new DataView(buf.buffer, buf.byteOffset, buf.byteLength);
  }

Then decode works fine.
