d9e727050c video: implement webp decoder around libwebp-sys2 crate
Unlike webpdec from -bad, this element inherits from GstElement
and can decode animated webp data.

77bf0c945e text: new element for text processing: regex
The element expects an array of "commands", as GstStructures,
in the form:

operation, pattern=<pattern>, ...

The only operation implemented for now is replace-all, eg:

replace-all, pattern=foo, replacement=bar

Other operations can be implemented if useful in the future,
eg. "match" could post a message to the bus when the pattern
is encountered.

The main use case for this is automatic speech recognition,
as implemented by eg awstranscribe as users may want to replace
swear words with tamer language.

Commands are applied in order.

The interface is usable through the CLI with the usual escaping
strategies, though trying to pass in actual regular expressions
through it is a bit tricky, as this introduces yet another
level of escaping.

b062f63ec3 Add new text/json crate
This new crate consists of two elements, jsongstenc and jsongstparse

Both these elements can deal with an ndjson based format, consisting
for now of two item types: "Buffer" and "Header"

eg:

{"Header":{"format":"foobar"}}
{"Buffer":{"pts":0,"duration":43,"data":{"foo":"bar"}}}

jsongstparse will interpret this by first sending caps
application/x-json, format=foobar, then a buffer containing
{"foo":"bar"}, timestamped as required.

Elements further downstream can then interpret the data further.

jsongstenc will simply perform the reverse operation.
