New Feature: Updated degradation estimation (with uncertainty) plus full loss factor analysis

[bmeyers]

Adds a new algorithm to solardatatools.algorithms called LossFactorAnalysis. This implements a signal decomposition algorithm for estimation of degradation and soiling losses in unlabeled daily energy production data. Model is of the form

y_t = x_t * d_t * s_t * c_t * w_t, for t \in K

where y_t [kWh] is the measured real daily energy on each day, x_t [kWh] is an ideal yearly baseline of performance,
and d_t, s_t, and w_t are the loss factors for degradation, soiling, capacity changes, and weather respectively. K is
the set of "known" index values, e.g. the days that we have good energy production values for (not missing or
corrupted).

Monte Carlo sampling of the data and problem parameters is used to estimate the degradation rate and its uncertainty. This algorithm has be integrated with the `DataHandler class.

@pluflou the PyPI test build didn't like the github link in the requirements file:

error in solar-data-tools setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Parse error at "'+https:/'": Expected stringEnd
Error: Process completed with exit code 1.
