This upgrade came with a number of new lints that needed to be fixed across the code base. Primarily: explicit return types on functions, and explicit visibility modifiers on class members.
Splits out the room locartion parsing from everything else to avoid
one function that fills out different parts of its return struct
depending on its args.
We'll always have matrix-widget-api as a dep through js-sdk so also
specifyin it ourselves just means we'll end up using a different version
when the js-sdk upgrade their copy and get wierd errors. We could add a
peerDependency if we really felt the need?
This was trying to get the room alias, which causes the config to be
read. We don't need the room alias here though, so pass the flag to
not return it.
* Make the embedded mode screen sharing a request-each-way rather
than request-and-reply, since replies time out and so can't wait
for the user.
* Try normal screen sharing first, then fall back to using the widget
API if it fails (for lack of a good way of detecting when we
should be using the widget API).
