Upgrade to java 14

• dropped "structs"
• replaced innoficial API usage for offheap and mmapped files by new "foreign memory access" API which is included in JDK 14's inkubator module. First impression: Oracle did an excellent work on this, performance is on par with older "Unsafe" hacks and some use cases even perform better. Only issue: "Why took this so long" ;)

Uploading fst-2.47.zip…
see release notes for 2.46, this one fixes accidental use of 1.8 api

Update + Bugfix

• fixed a regression regarding unmodifiable map in 2.45
• fix for JSon unmodifiable collection serialization moved to JSon-Configuration only (thanks to @lachty, @vivimice, @jkubrynski, @johnou )
• moved to objenesis 2.4 for Android N compatibility (credits @Wavesonics and others for hinting out + support)

bugfixes

• includes bugfixes contributed by bradedelman and jkubrynski (thanks)
• replaced getJSonConfiguration with getJSonNoRefConfiguration (json encoding supporting shared refs is still available via the parametericźed factory method)
• renamed 'fastbinaryconfiguration' to 'unsafeconfiguration' to encourage usage of getDefaultConfiguration
• added a change which will enable updates without breaking backward compatibility

this release breaks binary compatibility to prior releases, you cannot read streams written with older versions of fst.

use the relocated version of fst 2.44 provided in the 2.44 release to convert data serialized with prior versions toward this release
