Linking sidecar files

[in03]

2 source files have existing but unlinked proxy media.
Would you like to link them? If not they will be re-rendered. [y/n]: y
[09:32:11] ERROR    Failed to link 'my_test_file.mxf.xmp' - proxy does not match source!                                    batch.py:222
1 existing proxies failed to link.
They may be corrupt or incomplete. Re-render them? [y/n]:

.xmp files are often written as sidecar files for .mxf by Adobe's encoders.
Linking should follow the extension whitelist.

For now workaround is to delete the xmp.
