[question] Using Yaw Pitch Roll from EXIF to quicker process and get real mesh orientation

[remmel]

Some Camera application such as Android OpenCamera can provide yaw, pitch and roll in EXIF when taking the picture.
Eg: "UserComment" "Yaw:177.50502,Pitch:-50.860384571572325,Roll:-0.8683256611851107"

Is that possible to use thoses information to :

1. Quicker the SfM step even if thoses information might be not totally accurate
2. Help to find the position and orientation of pictures which could not not be found using the normal process
3. Having the mesh properly oriented (not the top on the floor) using real orientation (could be done manually using the SfMTransform when [bug] Cannot xyz rotate with SfMTransform #1064 will be fixed)

Attached, an example of image taken with OpenCamera : IMG_20200913_142816.zip (zipped to avoid Github removing EXIF info)
EXIF metadata added by OpenCamera can be viewed using for example EXIF Pilot (not displayed in Windows File Explorer)
You need to enable that feature in OpenCamera to add that information
