Synop2bufr

Bug fix: empty lines in metadata file no longer causes error.

note: minor update due to failed release.

This release provides the following small fixes:

Default value of the --metadata option is now station_list.csv rather than metadata.csv to be consistent with the exercises and other modules.
The logging level in cli.py determined by an environment variable has now been given a default value "ERROR" in the case that no environment variable is present (for example, when pip installing the module rather than running from the Docker image).
Potential breaking changes

Update to pinned version of csv2bufr and wmo-im fork of pymetdecoder. Stricter error checking in pymetdecoder may break using previously working data files.
