- Support outdoor workouts in ZWO format (cadence targets are NOT exported)
- Fix a bug with ZWO with cadence export setting invalid values for AC-based targets

Fixed a bug for ZWO exports with cadence.

Add option for including cadence targets for ZWO exports.

- Ability to directly export workouts in the ZWO format
- Fixed an authentication issue on Firefox preventing exporting workouts

Added support for downloading activities as FIT files. Activity files include power, cadence, and heart rate data only. Sensor information is not included, due to lack of availability via The Sufferfest API.

Minor bug fix

Removed the "Fixed Zones" option, as it was not producing the intended workout targets. Show example ranges generated by the selected target options.

Show current version in the pop-up menu.

Add further customisation to the target power ranges. Can use a fixed value or custom percentage, for smaller or wider target ranges. Increasing the target range can be useful if you find it difficult to stay near the target power outdoors.

Fixed issues with generating corrupted workout files.

Added option to choose target power range as target + 10%, or fixed zones.

Fixed zones should be somewhat similar to those described at https://support.wahoofitness.com/hc/en-us/articles/7671514838674-Wahoo-SYSTM-Outdoor-Structured-Workouts. Target + 10% is the previous behaviour, and can result in lots of short intervals.
