Behav from HDF5 file inputs

[Miles-and-miles-away]

追加機能についての概要
It is common for HDF5 files to store the behavioural data. Behavioural data is often stored in table format, with headers. Currently Optinist can handle headers only in csv files. It should be possible to load behavioural data stored in hdf5 format and then select which rows and columns to use for analysis later.
This could be solved by fixing this issue
