Maya: better tile rendering support in Pype

[antirotor]

Tile rendering

This PR is changing way tile rendering work. Previously it was necessary to submit tile renders via Maya Deadline Submit plugin and then create publish job via Pype publisher. Now Pype itself will create tile jobs on farm. It is compatible with Draft Tile Assembler plugin and will by default use Pype's own assembler based on Open Image IO tool (ynput/pype-setup#62).

Tiles are specified on render instance:

Deadline limitation is that there can be only one Tile Job per frame, so Pype will create one tile job for every frame and for every tile job one assembly job. So for single frame there will be 1x Tile Job, 1x Assembly Job, 1x Publish Job and for sequence of 10 frames: 10x Tile Jobs, 10x Assembly Jobs and 1 Publish Job.

Configuration is written per Tile Job into txt files and submitted as AuxFiles as Draft Assembler expects.

To use Draft Tile Assembler, create preset override in pype-config/presets/plugin/maya/publish.json:

"MayaSubmitDeadline": {
    "tile_assembler_plugin": "PypeTileAssembler"
}

⚠️ Limitation: Pype Tile Assembler plugin only support tiles rendered as EXRs

Depends on ynput/pype-setup#62
Closes #438 as no validator is required
Resolves #297
