Fast Implementation of Base58 encoding

Fast implementation of base58 encoding in Go.

Base algorithm is adapted from https://github.com/trezor/trezor-crypto/blob/master/base58.c

Benchmark

• Trivial - encoding based on big.Int (most libraries use such an implementation)
• Fast - optimized algorithm provided by this module

Encoding - faster by 6 times

Decoding - faster by 6 times

Usage example

package main

import (
	base58 "github.com/VSmert/base58-for-tinygo"
)

func main() {

	encoded := "1QCaxc8hutpdZ62iKZsn1TCG3nh7uPZojq"
	num, err := base58.Decode(encoded)
	if err != nil {
		// treat error
	}
	chk := base58.Encode(num)
	if encoded == string(chk) {
		// handle success
	} 
}
