v2.0.1 - Breaking change, for v5.2 / V5-R4 specification support

WARNING: this version breaks only supports the latest v5.2 (aka v5-R4) models, and breaks all previous models. Moving forward we will only be supporting v5-R4

What's Changed

• Fix segment_count not properly moved onto device by @TearGosling in #37
• Full v5 r4 rewrite by @PicoCreator @harrisonvanderbyl in #44
• Dropped the v5beta2 folder
• bptt_truncate=true is enforced, until state gradients is supported by the cuda kernel
• Technically the non cuda kernel works, but its so slow (~100x slower) that you really should not train without GPUs

New Contributors / Acknowledgements

• @TearGosling made their first contribution in #37
• @harrisonvanderbyl who helped directly to debug the code, and for his RNN-Factory codebase which was used for reference
