Does Buffer have plans to support more encodings?

[alec-2018]

@svaarala,hello great duktape developer,Currently duktape's buffer only supports utf8, is there any plan to support more encoding methods, similar to node.js('ascii', 'ucs2', 'base64', 'binary', 'hex'). For example：

console.log(buf.toString('base64'));

can get the correct result
