Release 0.3.6

[felicitas215]

Changes

• fixed reverse strand padding for overlap
• fixed resume-training loading models in a frozen state so they couldn't learn; did not affect fine-tuning
• fixed Helixer not working with models trained on a different pool size than the default of 9 (all released models use that default, so they were not affected)
• bulk data read-in is now subsequence length dependent
• improved h5 file documentation
