Pose2sim

**Full Changelog**: https://github.com/perfanalytics/pose2sim/compare/v0.8.1...v0.8.3

What's Changed
* Save to c3d and convert trc to c3d by hunminkim98 in https://github.com/perfanalytics/pose2sim/pull/92
* Small fixes after last release (eg not all demo data were downloaded upon install)

**Full Changelog**: https://github.com/perfanalytics/pose2sim/compare/v0.8.0...v0.8.1

**New automatic post-synchronization tool:**
- Tried cross-corr for sum of keypoint 2D speeds
- Tried cross-corr for sum of keypoint vertical speeds
- Tried cross-corr for sum of keypoint vertical positions
- Tried idem with sum of all keypoints vs selected keypoints
- Tried idem with sum of weighted selected points (L190 synchronize_cams_draft deleted)
- Tried idem with only right/left side
- Tried idem with frames around a specified time
- Tried cross-corr for each kpt, select top N highest correlations, take median offset (L244 synchronize_cams_draft deleted)
- Tried cross-corr for each kpt, weighted by correlation
- Tried threshold on vmax thresh
- Tried correlation threshold
-> Best results (accuracy, simplicity, speed): **sum of vertical speeds.**
Default: all keypoints, all frames. User can also choose specific keypoints at specific instants.


**Single-trial mode:**
- Batch mode still available
- Also works with a simpler folder structure, filled with a Config.toml file, a calibration folder, and a pose folder

What's Changed
* Process non filtered data if there is no data filtered in folder by ANaaim in https://github.com/perfanalytics/pose2sim/pull/86
* objp should not be objp_not_used by ANaaim in https://github.com/perfanalytics/pose2sim/pull/91
* Synchronization & single-trial mode by davidpagnon in https://github.com/perfanalytics/pose2sim/pull/94


**Full Changelog**: https://github.com/perfanalytics/pose2sim/compare/v0.7.2...v0.8.0

Calculation of the distance between epipolar lines (simple dot product, so quite fast) -> affinity matrix -> association across views (inspired by the easymocap approach)
Association across frames is done in triangulation.

Used to be based on a very computationally ineffective combinatory approach.

For a very challenging scene: 1h30 minutes -> 2 minutes.
As fast as easymocap, and more robust on my test scenes.



What's Changed
* Change of the testing of Calib and calib to work properly by ANaaim in https://github.com/perfanalytics/pose2sim/pull/78
* Synchronize multi cams based on keypoints speed. by hunminkim98 in https://github.com/perfanalytics/pose2sim/pull/76
* Faster and more robust multi-person analysis by davidpagnon in https://github.com/perfanalytics/pose2sim/pull/85


**Full Changelog**: https://github.com/perfanalytics/pose2sim/compare/v0.7.1...v0.7.2

Slightly improve multi-person
Converter to and from EasyMocap if too slow

**Full Changelog**: https://github.com/perfanalytics/pose2sim/compare/v0.7.0...v0.7.1

Sort people across view, and then across frames.

Set [project] multi_person = true for each trial that contains multiple persons.
Set [triangulation] reorder_trc = true if you need to run OpenSim and match the generated .trc files with the static trials.
Make sure that the order of [markerAugmentation] participant_height and participant_mass matches the order of the static trials.
