New Features:

• arm neon: support transpose mat4 with neon
• arm neon: multiply mat4 with vec4
• Swift Package Manager support, swiftpm package file with module map ( thanks to @smumryakW )
• meson: add 'install' option ( thanks to @Akaricchi )  

  This is useful for people who want to use cglm as a meson subproject without polluting the main project's install target.

Bugfixes and Improvements:

• arm neon: move neon-scale to simd header
• fix docs for glm_vec2() ( thanks to @emersion )
• simd/x86: fix -Wcast-align warnings (gcc/clang) ( thanks to @Akaricchi )  

  This modifies glmm_{load,store}3 functions to make the compiler assume the v pointer is appropriately aligned for the type it is being cast to. Not tested with CGLM_ALL_UNALIGNED, but it probably doesn't matter.
