Batch oriented int encoders
This commit adds a tsm1 function for encoding a batch of ints into a
provided buffer.
The following benchmarks compare the performance of the existing
iterator based encoders, and the new batch oriented encoders. They look
at a sequential input slice, a randomly generated input slice and a
duplicate slice:
name old time/op new time/op delta
