Dark current correction fix

Added:

• Tests for compatibility with numcertain & pint

Fixed:

• Dark current correction now uses transmitted flux
  • Previously used pixel-wise flux

Correction Sequences

Added:

• Correction sequences from Pauw et al. (2017)
  • Instrumental background pauw_instrumental_background_sequence
  • Simple sample pauw_simple_sample_sequence
  • Dispersed sample pauw_dispersed_sample_sequence
• i22 corrections tutorial

Changed:

• Moved corrections to adcorr.corrections
• Split dev & docs extras
