Need C implementations of btoa and atob

[mlite]

function atob(, s: string): string

Decodes a string of data which has been encoded using base-64 encoding.

console.log(atob("aGVsbG8gd29ybGQ=")); // outputs 'hello world'

function btoa(, s: string): string

Creates a base-64 ASCII encoded string from the input string.

console.log(btoa("hello world"));  // outputs "aGVsbG8gd29ybGQ="

This one should be compatible with our license:
http://web.mit.edu/freebsd/head/contrib/wpa/src/utils/base64.c

We just need to extract it and add it's license.

This code should be added to the cee-utils repo.

This SO thread has benchmark different base64 implementations. https://stackoverflow.com/questions/342409/how-do-i-base64-encode-decode-in-c
