chore: rename imports from platform to influxdb
...
I did this with a dumb editor macro, so some comments changed too.
Also rename root package from platform to influxdb.
In interest of minimizing risk, anyone importing the root package has
now aliased it to "platform" so that no changes beyond imports were
necessary in those files.
Lastly, replace the old platform module to local path /dev/null so that
nobody can accidentally reintroduce a platform dependency while
migrating platform code to influxdb.

fix(encoding): Improve simple8b another 6%; fix inconsequential bug
...
simple8b encodes deltas[1:], thus deltas[0] >= simple8b.MaxValue is
invalid.
Also changed loop calculating deltas, RLE and max to be similar to
batch timestamp, for greater consistency.
Improvements over previous commit:

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:
