Proposed Feature: NO_COLOR console or logfile output

[taclane]

Trunk Recorder extensively uses ANSI color codes in logging statements to make the console output easier to read, but users should be able to disable them if desired.

Additionally, this behavior can create issues when combined with the logFile option, as the raw escape sequences may make the output difficult to parse or ingest (example below).

Proposed is a logColor setting to selectively disable color output to logfiles and/or the console.

• By default, color codes will remain enabled for console output, but now get removed from any configured logFile.
• This default will be overridden by the presence of a NO_COLOR environment variable. If the environment variable is set (and not NULL), it will disable color output to both the console and logfiles without needing to alter the config.json.
• If logColor is used in the config.json, that value will override the presence of the NO_COLOR env var. Per no-color.org recommendations, this is the desired behavior.

  How should configuration files and command-line arguments be processed in the presence of $NO_COLOR?
  User-level configuration files and per-instance command-line arguments should override $NO_COLOR.

Attached below is an example of the default setting, showing the simultaneous output of the console and logfiles. The color codes have been automatically removed from the logfiles without the use of additional tools or commands.

RegEx is dark magic and this is an amazing addition... thank you!
