Iris Calliope

bug fix

added option of calculating in dB space (seems more reasonable for biological signals, won't be dominated that heavily by the components on the low frequency range)

generate_proj_meta: fix to an error in the behaviour of combined EEG and widefield experiments, which caused only the first cell of a proj_meta file to be populated with EEG data

calc_widefield_act: reverted to and committed previous version again - sorry, this is more complicated since the 2ch case is mostly ignored when saving registration_parameters

calc_widefield_act: changed initial call to Adata class call; changed line 39ff to accommodate 1ch and 2ch cases
-heinmatt

added option for 2-color

added siteID input

Added the colourbar to plotting.

added handling of different types of act (act_ch525, act_ch610)
