Support passing an updated license database to pyspdxtools #888
Description
If spdx-tools has an outdated license database, it can fail to recognize a valid license.
Updating the package will fix this, but it would be convenient to be able to update the database independently.
Please consider providing an option to pass in the license database. get_spdx_licensing supports an optional argument to pass in the database path; this would need to get plumbed through LicenseExpressionParser, FileParser, JsonLikeDictParser, its various invocations in parse_from_file methods, parse_file which invokes all of those, and finally the pyspdxtools command line.
I'd be happy to file a PR doing this, if this would be welcome.
