[OSX-arm64] Reproduce the checksums of the libraries

[shpaass]

For security reasons, we need to reproduce the checksums for the library-versions that were added with the OSX-arm64 build.

In other words, we need the users of OSX-arm64 to go through the instructions in order to get five files and compile their hashes:

liblia.a
liblua.dylib
libSDL2.dylib
libSDL2_image.dylib
libSDL2_tff.dylib

You can get the needed hashes on Mac by running the command below on each file. The flag -a chooses the needed sha256 hashing algorithm:
shasum -a 256 /path/to/file

Based on #191, we expect the hashes to be the following:

bc6b8a37c4b70fa94f53950b35873d559f1492ae3cf274e96f1648ab7caf184a *libSDL2.dylib
68024446df6902bc6751f5e3a7e4f6042dc214354a0ba6e102e0ec0cd9899741 *libSDL2_image.dylib
f809c5aa87006a5b58a23b045c552b3a4fee930b356e5c69c73a15d0f226a699 *libSDL2_ttf.dylib
9671d806c9dddfa72736b2545b016dc1c58585397532587dff8b5ff058fad866 *liblua52.a
fd78a23f8c610909c4d2b4f85af308fd0e06b451d3e991697f3224cbf40e3bd4 *liblua52.dylib

If you get different hashes, then feel free to post them here too.
