Add licence

What about https://www.gnu.org/licenses/gpl-3.0.en.html @julesjacobsen @ielis ?

I think an open license is OK, since we definitely should put this library to Maven Central. However, are there reasons why not to use the license type of Phenopacket-schema?

[julesjacobsen]

It's a copyleft licence. This isn't the most open and permissive of licences and requires that other software using the library also be GPL-v3. (https://www.gnu.org/licenses/rms-why-gplv3.html)

I suggest we should go with MIT / Apache as these are fully open licences and are commercial friendly which is essential if we want people to adopt this as widely as possible.

Actually who is the copyright owner? I think this should be a GA4GH copyright? Otherwise it'll be JAX and QMUL.
