Update V3.2.5: remove of old, not needed function and dependencies, update of download_background function

IR_image_tools: in derive_wetted_area_per_module() if heat_flux < 0 exist, set all heat fluxes lower than noise_threshold to 0

IR_image_tools: changed import of os for more flexibility
IR_image_tools: new function read_finger_info() reads intup files with parameters of the fingers as defined in the heat flux mapping
IR_image_tools: new function derive_wetted_area_per_module() calculates the wetted area given a numpy array with THEODOR results and mapping reference arrays as stored on the archive
downloadversionIRdata: small fixes to parameter structure in calls and messages, variation of example section
new input files in .\data: finger_infor_TDU.csv and finger_info_HHF.csv (used for wetted area calculation)

cosmetic overhaul: made output control with verbose consistent, unified output format, tidied up string generation, removed redundant get_OP_by_time() from downloadversionIRdata

Update V2.9.0: change multiprocessing to multithreading, performance improved, less archivecalls per download

Update to V2.8.0 (this time complete): FLIR data can now be downloaded, port accepts now strings and numbers

update to V2.5.3, add the version number, bug fixes and imporved exception handling for downloadversionIRdata

bug fixes for AEF41 in the bad Pixel correction, bug fixes because of changes in json files downloaded from the Archive

improved bad pixel correction, added reading of bad_pixel file; added output control (verbose level); apply_calib_on_raw now checks for inf in gain and offset;small bugfixes
