Encoder / Decoder classes dont work with `new ExtensionCodec()` for handling Set and Map in typescript

[noahehall]

issue:

how do we use ExtensionCodec with En/Decoder classes? they dont accept an options 2nd param

even if we pass the extensionCodec in the constructor, and continue as normal, encoding fails

import {
  Encoder,
  Decoder,
  encode,
  decode,
  ExtensionCodec,
} from "@msgpack/msgpack";

// Encoder && Decoder doesnt work with extensioncodec
const extensionCodec = new ExtensionCodec();
const decoder = new Decoder({ extensionCodec });
const encoder = new Encoder({ extensionCodec });

// Set<T>
const SET_EXT_TYPE = 0; // Any in 0-127
extensionCodec.register({
  type: SET_EXT_TYPE,
  encode: (object: unknown): Uint8Array | null => {
    if (object instanceof Set) {
      // return encoder.encode([...object], { extensionCodec }); // <-- when using encode fn
      return encoder.encode([...object]);
    } else {
      return null;
    }
  },
  decode: (data: Uint8Array) => {
    // const array = decoder.decode(data, { extensionCodec }) as Array<unknown>; // <-- when using decode fn
    const array = decoder.decode(data) as Array<unknown>;
    return new Set(array);
  },
});

// Map<T>
const MAP_EXT_TYPE = 1; // Any in 0-127
extensionCodec.register({
  type: MAP_EXT_TYPE,
  encode: (object: unknown): Uint8Array => {
    if (object instanceof Map) {
      //  return encoder.encode([...object], { extensionCodec }); // <---- when using encode fn
      return encoder.encode([...object]);
    } else {
      return null;
    }
  },
  decode: (data: Uint8Array) => {
    //  const array = decoder.decode(data, { extensionCodec }) as Array< // <--- when using decode fn
    const array = decoder.decode(data) as Array<
      [unknown, unknown]
    >;
    return new Map(array);
  },
});

It seems to be the same bug in #195

Will fix it soon.
