redistmetrics 1.0.4

Add generic function to tally a varible by plan
Massively speed up calculation of county/admin/muni splits as well as plan reindexing
Fix rare edge case in prep_perims() where a shape that is Queen's-contiguous to one other shape and contiguous to nothing else causes a loud failure when creating the perimeter output.

Minor improvements to compactness functions by removing costly unions where collections are sufficient.
Adds support for multi-threaded VI calculations.
Uses new logo to match the updated redist logo.
Implements an experimental basic fuzzy splits function for non-nesting geographies.

Makes ncores argument work for prep_polsby().
Speed improvements for compactness functions in serial.
C++ header-only interface for some functions
Reverses part_tau_gap() sign so positive is pro-Republican bias.
Improves usability of by_plan() by allowing for measurements to be repeated. Instead of reducing the vector length only if every entry is repeated the same number of times, it does it by the greatest common divisor.
Corrects documentation indicating that some inputs need to have sf geometry when it is not used.
Relicense under MIT License
Adds admin_splits_total() to count total unique district-admins.

Reverses part_bias() sign so positive is pro-Republican bias.
Reverses part_egap() and part_egap_ep() sign so positive is pro-Republican bias.
Fixes bug where splits_admin() plans input needed to be sequentially numbered (#10).
Allows planarizing warnings to be silenced when epsg = FALSE (#11).
Makes ncores argument work for compactness functions.
