Ability to clear recording buffer whilst recording

[vsboost]

This is more a feature request rather than a bug.

Would it be possible to clear the recording buffer whilst samples are being captured?
Reason being is sometimes i'm not sure when a signal will be present and the recording gets quite large, it would be good to be able to press clear whilst its recording to start fresh if you know what i mean.

Pressing stop and clear and start takes too long for the SDR (lime in my case) to start recording so there is a chance signal could be missed.
