v0.10.0

Changed

• several modules containing implementations of fragmentomic features or
  utility functions have been made internal. This means there is now only one
  obvious import for each function. For example, multi_wps is imported from
  finaletoolkit.frag, and no longer can be imported from
  finaletoolkit.frag.multi_wps
• The CLI now uses lazy importing, drastically speeding up finaletoolkit when
  called from a command line.
• Added negative_strand option for end-motifs related functions. When
  used in conjunction with both_strands, only end motifs on the negative
  (Crick) strand are considered in calculations.
• Renamed fraction_high and fraction_low in utils.utils.frag_generator
  to min_length and max_length.

Fixed

• deprecated arguments for end-motifs had default values which could
  lead to an error. This is fixed.
