[Feature] PPG peak detection: Add MSPTDfast algorithm (Charlton et al., 2024)

[peterhcharlton]

Added MSPTDfast algorithm (v.1.1) for PPG beat detection.

Description

This PR aims at adding the MSPTDfast algorithm (v.1.1) for PPG beat detection. This algorithm is a python implementation of the Matlab algorithm available at: https://github.com/peterhcharlton/ppg-beats/blob/main/source/msptdfastv1_beat_detector.m .

Proposed Changes

I changed the ppg_findpeaks() function by adding this additional beat detection method.
