To aid in composability, these methods no longer write their own length. This is especially useful for text formatted arrays and may be useful for future database/sql compatibility. It also makes the code a little simpler as the types no longer have to compute their own size. Along with this, these methods cannot encode NULL. They now return a boolean if they are NULL. This also benefits text array encoding as numeric arrays require NULL to be exactly `NULL` while string arrays require NULL to be `"NULL"`.
