Add support for higher vram GPUs (24GB+)

[aperire]

Hi, I understand that fluxgym was designed to support low vram cards to train Loras. However, due to it's simple UI, there are a lot of users who have 4090 or ones waiting for 5090s (36GB vram) who are willing to use Fluxgym.

Support for higher vrams would be a great decision without sacrificing any convenience for other users.

Need this. Please add 24, 36, 48 or a field to enter the custom GPU memory size. Much needed when using platforms like Vultr or Runpod. Thanks!
