Tune sqlite to use write-ahead-logging
...
Enable the following pragmas: synchronous=NORMAL, journal_mode=WAL.
This offers a significant speedup to INSERT times compared to
synchronous=FULL, and is roughly the same as synchronous=OFF
but should be a bit safer.

Big rework of stream_insert_context and places that use it.
...
Things are now block-focused, rather than line-focused. This should
give a pretty big speedup to inserting client data, especially when
inserting preformatted data.

Move ASCII data parsing from the server to the rocket interface.
...
The server buffers the string and passes it to nilmdb. Nilmdb passes
the string to bulkdata. Bulkdata uses the rocket interface to parse
it in chunks, as necessary. Everything gets passed back up and
everyone is happy.
Currently, only pyrocket implements append_string.

Convert times to microsecond precision strings more consistently.
...
Use a new helper, nilmdb.utils.time.float_to_time_string().
This will help if we ever want to change representation (like using
uint64 microseconds since epoch, which saves us from having to
waste bits on the floating-point exponent)
