Functions to model transmission electron microscopy signal degradation as a function of cumulative electron dose and stage tilt

Functions

`calculate_critical_dose_per_frequency`	Calculate critical dose for spatial frequencies following Grant and Grigorieff 2015
`calculate_dose_mask`	Create mask as intersection of non-zero dose weights and circular mask
`calculate_dose_weights`	Calculate weight associated with spatial frequencies given cumulative dose and critical dose
`calculate_spatial_frequencies`	Calculate spatial frequencies for image of width D-1 pixels with sampling of angpix Å/px
`calculate_tilt_weights`	Calculate weight per tilt image associated with higher tilt increasing optical path length and decreasing SNR
`combine_dose_tilt_weights`	Merge dose weights (per frequency and per tilt) with tilt weights (per tilt) for single output array
`plot_weight_distribution`	Plot distribution of dose weights across tilts in the spirit of https://doi.org/10.1038/s41467-021-22251-8
