v1.5.0

Added

• Add support for ESRGAN+ models, Real-ESRGAN models (including 2x and 1x if pixel-shuffle was used),
  and A-ESRGAN models.
• Add support for Newer-New-arch in ESRGAN new-to-old state dict conversion.

Changed

• Rework model/arch file system structure to /models, /models/blocks and /models/ESRGAN.
• Rework ESRGAN architecture as a singular class, with all ESRGAN-specific operation done within it.
• Move ESRGAN-specific blocks within ESRGAN.py.

Removed

• Removed some unused blocks from RRDBNet.

Fixed

• Ensure clip parameter of VSGAN is a VapourSynth VideoNode object (a clip).
• Move RGB clip check to the constructor of VSGAN rather than run().
