5.7.4 (#642)

* update openvr 1.26.7

* ignore chaperone play area error, as it should not effect chaperone, and it frequently occurs with some meta to pcvr configurations

* replace old seated origin call with new reset zero pose call

* change zero offsets to new command

* adjust camera settings to new version of openvr 1.27

* fix save error

* increment version 5.7.4
