open-vins mask file location

[Jeremy Frederick]

Hello,

In the QVIO service, the config file has a line item for path to mask to use for QVIO. On the new, open-vins service, the config file has a line item for enabling the use of a mask, but does not have a line for specifying the path to the mask. Where do we identify the path to the mask file used, or otherwise where should the file be positioned. We will be using two masks for two separate tracking cameras.
