- utils/signal.py: waveforms, constant- and variable-amplitude signals, common period of periodic signals. - data_parsing/loads.py: Channel, LoadCase and LoadHistory, with export to Voigt stress. - Tests for both modules and a usage example with 7 load cases.

Summary
Adds a way to describe loads: time signals, load channels and load cases. The results can be exported as Voigt-notation histories.
