Migrate From ckb-sdk-utils to Lumos

Summary

In order to unify CKB development ecology, the functions of ckb-sdk-utils will be migrated to @ckb-lumos/lumos, most of the functions can be replaced by the corresponding functions directly, but the normalize.ts need to be rewriten with @ckb-lumos/codec.

@lumos/codec

@lumos/codec provides a set of functions to pack(encode) and unpack(decode) data. related link: https://github.com/nervosnetwork/lumos/blob/develop/packages/codec
