c88277a898 [filamesh] Add option to skip secondary UV coords (#6398) 
Also added error and exit for when there's a mismatch in the
number of vertices vs. the number of UV coords (either primary or
secondary).

f876171239 filamesh tool now generates dummy UV's if necessary. 
filamesh requires UV's but some glTF test models, like CesiumMilkTruck,
do not provide UV's on nonlit parts (e.g. the truck windows). This makes
it so that these assets can be converted to filamesh somewhat more
gracefully.

422bf8631b Small assimp fixups for glTF => filamesh conversion. 
This fixes some crashes when trying to convert CesiumMilkTruck.

2633edf2c4 Changed MeshAssimp to use snorm16 if uv values are in the range [-1, 1] (#592) 
* grouped MeshAssimp arguments into struct

* added snormuv optimization to MeshAssimp and changed snormuv optimization range from [0, 1] to [-1, 1] in filamesh

beaf751604 filamesh: Compress attributes individually. 
This further reduces compressed suzanne from 333489 bytes to 272761.

Tested with vk_hellopbr and tutorial_suzanne.html

6c55b3b989 filamesh: Add support for COMPRESSION. 
Note that the WebGL build uses filameshio, but Android does not. Our
Android samples therefore do not yet understand the compressed format.
For web, I measured the before / after:

```
BEFORE: filament.wasm = 505796, suzanne.filamesh = 521476
 AFTER: filament.wasm = 510915, suzanne.filamesh = 333489
```

0af274fe0e filamesh: introduce MeshWriter class. 
This simplifies main.cpp so that it only does assimp stuff.

61992f556c Add unit test for filamesh. 
The motivation behind a new regression test is the fact that we will
soon be adding compression features to filamesh.

aa3a7085cc Factor out common filamesh / meshio code. 
This creates a filamesh namespace and removes several duplicated
classes, including Box and filamesh::Header.
