[Feature] Merging Peleton data into existing activity for having additional data

[RicardoNiepel]

Is your feature request related to a problem? Please describe.
Current sync adds Peleton activities to Garmin Connect, only using data from Peleton API, ignoring matching Garmin activity which maybe contains other data.

If you wear a Garmin watch during the training, the original activity contains additional data like respiration rate, sweat loss, stamina, body battery and recovery hr.

Describe the solution you'd like

• Look for similiar activities already existing in Garmin Connect during sync
• Read additional data of the original activity
• Merge this data into the new activity created from the Peleton data
• Upload the new activity, delete the original activity
