// Implement various base64 fixed-size array helpers

/// Utility for calculating base64 encoding lengths.
///
/// In the Base64 encoding each character is used to represent 6 bits (log2(64) = 6). This means
/// that 4 characters are used to represent 4*6 = 24 bits = 3 bytes. So you need 4*(`n`/3)
/// characters in order to represent `n` bytes, and this needs to be rounded up to a multiple of 4.
/// The number of unused padding characters resulting from the rounding will be 0, 1, 2, or 3.
