New version 1.9.3

[karrmagadgeteer2]

• Changed instantiation of OpenFrame to use deepcopies of constituent OpenTimeSeries. Rationale due to resample functions affecting original input series which will affect the behaviour of other OpenFrame objects where they are used
• Added method multi_factor_linear_regression to the OpenFrame class
• Added method as argument in align_index_to_local_cdays
• Changed default argument for histnorm in plot_histogram from percent to probability
• Pinned plotly histogram histfunc argument to 'count'
• Removed unnecessary .ffill() and unnecessary mypy blanket ignores
• Changed rolling_vol to be based on np.log(series).diff() instead of series.pct_change(). Also set ddof as argument to highlight the default used
• Widened sortino_ratio_func to allow kappa3 ratio calculation
• Potentially breaking change - Refactored downside_deviation_func into lower_partial_moment_func in order for it to be used in kappa3 ratio calculation.
• Added Kappa-3 ratio as a property
• Code cleanup in ewma_risk calculation
• Updated Poetry to version 2.1.4 in project script files
• Miscellaneous lockfile updates to check project against new versions of dependencies
