Warnings from Node

[AdamW19]

When we merge #46 into main we will get the following warnings from node:

  Line 72:18:  Unexpected control character(s) in regular expression: \x00, \x0f  no-control-regex
  Line 73:18:  Unexpected control character(s) in regular expression: \x10, \x1f  no-control-regex
  Line 86:18:  Unexpected control character(s) in regular expression: \x00, \x0f  no-control-regex
  Line 87:18:  Unexpected control character(s) in regular expression: \x10, \x1f  no-control-regex

I don't know if we want to flat out ignore these warnings (Rick disagrees). We definitely shouldn't include any weird control chars in a regex but I don't foresee this occurring in normal operations.
