fix(compressor): remove logging.basicConfig from library class __init__

logging.basicConfig() in TrajectoryCompressor.__init__ overrides the
root logger configuration every time the class is instantiated. Library
code should use logging.getLogger(__name__) and let the application
entry point configure the root logger.

Fixes inconsistent log formatting when the compressor is used alongside
other logging configuration in the gateway.
