Fixes #904

I find the times to be comparable for the regal bundle + a simple violating file.

regal $ hyperfine --warmup 3 './regal-main lint . --disable-all --enable=pointless-reassignment' './regal-pointless lint .
 --disable-all --enable=pointless-reassignment'
Benchmark 1: ./regal-main lint . --disable-all --enable=pointless-reassignment
  Time (mean ± σ):      1.171 s ±  0.077 s    [User: 6.188 s, System: 0.192 s]
  Range (min … max):    1.108 s …  1.370 s    10 runs
 
Benchmark 2: ./regal-pointless lint . --disable-all --enable=pointless-reassignment
  Time (mean ± σ):     665.8 ms ±  11.3 ms    [User: 2891.0 ms, System: 100.2 ms]
  Range (min … max):   644.2 ms … 688.2 ms    10 runs
 
Summary
  ./regal-pointless lint . --disable-all --enable=pointless-reassignment ran
    1.76 ± 0.12 times faster than ./regal-main lint . --disable-all --enable=pointless-reassignment

Fixes StyraInc#904
