Utility library to convert data to base64url format

## NAME

dnsjit.lib.base64url - Utility library to convert data to base64url format

## SYNOPSIS

  local base64url = require("dnsjit.lib.base64url")

### Encoding and decoding lua strings

  local encoded = base64url.encode("abcd")\
   local decoded = base64url.decode(encoded)

### Encoding C byte arrays

  local pl  -- pl is core.object.payload\
   local encoded = base64url.encode(pl.payload, pl.len)

## DESCRIPTION
