Bug#955421: licensecheck: parse markdown formatted email address entries in copyright

[Dominique Dumont]

Package: licensecheck
Version: 3.0.46-1
Severity: wishlist

Dear Maintainer,

rollup-plugin-terser main README  file [1] is 
written in markdown and contains:

  MIT © [Bogdan Chadkin](mailto:trysound at yandex.ru)

With --deb-fmt option, this information is extracted by licensecheck
as is, i.e. with markdown syntax:

$ licensecheck -m -r --copyright --deb-fmt --encoding utf-8 README.md 
README.md       UNKNOWN [Bogdan Chadkin](mailto:trysound at yandex.ru)

Without --deb-fmt option, this information is *not* extracted:

$ licensecheck -m -r --copyright --encoding utf-8 README.md 
README.md       GENERATED FILE  *No copyright*

Could you:
- make licensecheck behavior consistent with or without -deb-fmt option
- convert markdown syntax to canonical copyright line

All the best
