Mark Rushakoff d73d73c0d4 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.

Stuart Carnie bef0577206 fix(simple8b): Fix incorrect encoding for a run of 119 or 239 1s
If 120th or 240th value is not a 1, k still passes the check in the
switch, causing the last value to be lost. If this value occurs at
the boundary of a block, the max time will be incorrect, resulting in
compaction failing to make forward progress.
