Vivia Nikolaidou 063871a1eb togglerecord: Add support for non-live inputs
Live input + is-live=false:
    While not recording, drop input
    When recording is started, offset to collapse the gap

Live input + is-live=true:
    While not recording, drop input
    Don't modify the offset

Non-live input + is-live=false:
    While not recording, block input
    Don't modify the offset

Non-live input + is-live=true:
    While not recording, block input
    When recording is started, offset to current running time

# togglerecord
A multistream valve-like plugin that ensures multiple streams start/end at the
same time.
It supports both live and non-live input and toggles recording via the
`record` property. Live inputs will be dropped when not recording, while
non-live inputs will be blocked.
## Use cases
The `is-live` property refers to whether the output of the element will be
live. So, based on whether the input is live and on whether the output
`is-live`, we have these four behaviours:
- Live input + `is-live=false`:
- While not recording, drop input
- When recording is started, offset to collapse the gap
- Live input + `is-live=true`:
- While not recording, drop input
- Don't modify the offset
- Non-live input + `is-live=false`:
- While not recording, block input
- Don't modify the offset
- Non-live input + `is-live=true`:
- While not recording, block input
- When recording is started, offset to current running time
