Handle SPDX-style author lines

Author information using SPDX tags (as written by Lokalize)
is now correctly parsed. That is, a line like this

  # SPDX-FileCopyrightText: 2024, 2026 John Doe <[email protected]>

is handled exactly the same as a line like this

  # John Doe <[email protected]>, 2024, 2026.

To accommodate other PO editors, the parsing is slightly more
flexible than what is necessary for handling the syntax
used in Lokalize (e.g., en-dashes instead of hyphens in year
ranges are accepted).

However, there is no attempt to handle SPDX tags in other formats,
e.g., ‘incomplete’ tags without an email address or a copyright year.
(The SPDX-FileCopyrightText is in theory a free-form field.)
These non-standard tags will continue to be ignored or result
in an error/warning from Pology’s default author line parsing.
