Reconsider licensing because of native builds

[szape89]

Hi @MenoData,
First of all, thanks for all your work!
As I've read you "have no commercial motivation" and open to change licensing, although the issue is quite old: #12
I suggest to reconsider the current licensing (LGPLv2.1) in the name of "wide-spread distribution and popularization as much as possible". Java native builds are getting more and more popular, but the license in its current state does not allow to use your work with them (GraalVM, Spring Native, Quarkus, etc.). Hibernate has the same licensing but they explicitly allow this, probably that would be the easiest solution. You can read more about this here: https://hibernate.org/community/license/
Thank you for your consideration!

Hey, I would like to use different calendars in https://github.com/focus-shift/jollyday which is under the Apache 2 Licence, but because of the LGPLv2.1 I cannot use it. If there would be a way to publish under Apache 2 or something compatible, I would be very happy :)
