V1.2.0 (#50)

* removing scripts folder. Renaming IndexFormat_I32_UINT -> IndexFormat_UINT_32

* adding logging support

* adding tests

* bumping version, fixing minimal sample test

* Compile fixes

* fixing tests on gcc. Renaming test for logger

* Changing to correct version number (1.2.1 -> 1.2.0)

* removing unused function

* adding support for UNORM16 and FP16 uv formats

* Increasing consistency by adding omm_ prefix to all shader files

* compile fix

* Compile fix #2

* chaning from bitwise to logical operators for consistency

* Adding TexCoord enum shader side

* Increasing stride between consecutive execute indirect calls

* Updating to latest ShaderMake. Removing benchmark

* updating submodules

* fixing comment
