Nemesis Retaliation custom insert

This is a custom insert Nemesis Retaliation Gamefound ed.

This is an almlost complete rework of great [Hextra insert in Makerword](https://makerworld.com/es/models/1667725-nemesis-retaliation-insert#profileId-1765161). I made this with these goals in mind:
* Allow smaller printers (I have a 220x220 bed in my Ender 3 v3 KE)
* Keep original backpacks (Hextra discards them)
* Less plastic use as I don't have acrilic tokens and I've reduced the use of card holders (this could be improved enven mode, but I'm too lazy and want to play)
* Sangrevore minis separated by type.
* Premium sleeved cards (maintain this possibility of the original insert for big cards, mini cards can't be sleeved neither in original nor my version)
* Allow vertical storage as original version

NOTE: There are two versions of the enemy token trays, one in English and the other in Spanish. The STL file name indicates this.

Need to print:
- 1x everything, except
- 2x tokens
