Implement base64-encoded arrays

This implements base64-encoded arrays, which can be read much faster than delimiter-separated text arrays. This should eliminate a large fraction of a second of overhead from early warning alerts.

This encoding is specified in https://dcc.ligo.org/T990023.

See emfollow/gwcelery#885.
