Mountain Project Tick Cleaner

About

This extension deletes repeated ticks on Mountain Project. For each route that you've climbed, all ticks except for the "best" one will be deleted. "Best" is defined as follows:

* First, ticks' numbers of pitches are compared. Ticks with more pitches are considered better.
* Next, ticks' styles are compared. Onsights are considered the best, then clean sends, and so on.
* Next, ticks' dates are compared, with earlier ticks considered better.
* As a final tiebreaker, ticks' IDs are compared. A lower ID (indicating
  that a tick was recorded earlier) is considered better.

This extension as written as a companion to https://mpticks.web.app/ . The general idea is that you can periodically import your Mountain Project ticks into mpticks and then use this extension to delete repeated ticks from Mountain Project.

Changes:

- 0.6: Properly escape query parameters so that email addresses containing pluses will work.
- 0.5: Switch to Manifest V3.
- 0.4: Sort "Lead" before "Fell/Hung".
