This adds a geolocation entry to the REST API. The geolocation can
be set or cleared by a PUT request, and the current geolocation is
used to populate the "core:geolocation" SigMF key if it is available
at the start of the recording.

This adds a HTTPS server to maia-httpd. By default it listens on
port 443. It uses a self-signed certificate that is included in the
application binary. The main intended use of this feature is the
maia-wasm Geolocation API functionality, which browsers refuse to
use over HTTP connections.

If the app is using HTTPS, then the websocket should use wss://
instead of ws://

This adds support for setting the maia-httpd REST API geolocation
and recording metadata geolocation by using the HTML5 geolocation
API.

The recent addition of HTTPS support to maia-httpd has caused the
size of the binary to grow from ~4.9 MB to ~7 MB. This causes the
resulting plutosdr-fw image to no longer boot (probably an
out-of-memory error when copying the rootfs to ram). This enables
stripping of all the symbols, which decreases the binary size to
~6 MB.

Instead of embedding a self-signed SSL certficate, provide command
line parameters to load certificates from files.

A certificate signed with a trusted CA is needed to install maia-wasm
as a PWA (Progressive Web App), because current web browsers require PWAs
to be accessed by SSL with a trusted certificate (not a self-signed
certificate). This opens up a way to install maia-wasm as a PWA, but
it requires the user to trust and add a CA certificate manually in
their device. A startup script will generate a suitable CA and web
server certificates on boot and store them in persistent JFFS flash.
The user can also replace these with their own (by doing scp or
similar).

Add a couple of min-width: 0px; to make the settings dialog look
better in a very narrow viewport.

Add an "Other" tab with a link to the CA certificate and the
maia-wasm version. In the future this tab can also contain versions
of other components, but they need to be exposed in the maia-httpd
API.
