v0.10.2

Fixed

• changed default args for wps would lead to errors. Now wps defaults to
  LWPS fragment lengths (120-180nt).

Changed

• made finaeltoolkit.utils.typing public. This is a module containing some
  useful type aliases
• minor formatting and typing changes
• renamed fraction_low and fraction_high to min_length and max_length
  for .utils.frag_array and .frag.wps. wps retains the deprecated arg names
  but issues a warning.
