Chris Tate 975270cef5 Decode base64 eight characters at a time ...

Buffer.from(text, "base64" | "base64url") decoded each four-character
group with four lookups and a sign test, then stored its three bytes one
at a time. The decoder now first takes complete groups two at a time:
each character's value comes from a table that holds it already shifted
into place within its group's 24 bits, a single bit test covers all
eight characters, and each group's three bytes go out in one four-byte
store whose last byte the next store overwrites. A group with any other
character (padding, whitespace, an invalid character) takes the
previous path, and the two-group step resumes after it, so line-wrapped
text keeps most of the gain. The destination already holds two spare
bytes, which cover the extra store byte.
