Blechpy

-------------------
- Store both BIC and Cost on each iteration of fitting HMM in history
- Critical Bug Fix:
- Remove use of tempfile when waveform plotting
- Prevents errors while clustering

-------------------
- Minor debugging
- Fix to blech clustering, data loading
- Adding functions to plot hmm output

-------------------
- Trying to get BlechClust object to adpat if experiment root dir has changed
- Updated requirements

-------------------
- Correction to how spike time autocrrelation and xcorr are computed (from counts -> spike/s)
- Add wavelet transform view and split by rec to spike sorting
- Add umap clustering option to dataset object
- Unfinished module for Poisson HMM decoding of spike data
- Expanded functionality of h5io.get_spike_data to provide data for multiple neurons and digital inputs at once
- Fix adding and removing experiments from project datastructure
- Spike sorting no longer saves 0 spike clusters
- Fix experiment _change_root to update rec_labels

-------------------
- Minor fix to project
- Fix imports for project
