v0.7.0

Strom 0.7.0 is a big release: 93 merged pull requests since 0.6.11, with the two 0.7.0 alphas in between. A lot has changed, so read through the list below before you upgrade, and test your flows on it before you take it on air.

Highlights

• Stinger transitions on the vision mixer: classic, track matte and mask only, with a clip library, cue and take, and example clips you can render from the panel (#1010).
• Live Recorder, a new recorder block where a quiet track holds nothing up, writing fragmented MP4, Matroska or MPEG-TS (#1034).
• HTML Input: render a web page as a source, and drive the page remotely (#879).
• Media Player plays live streams, extra tracks and URLs (#945), and media files can be downloaded from a URL, with upload progress (#1043).
• GPU paths: CUDA-memory inputs on the GPU vision mixer, NVDEC frames kept on the GPU, and GPU inputs in any pixel format (#948, #952, #1033).
• Audio: mixer and router inputs are resampled to one configurable sample rate (#946).
• WHIP and WHEP are much more robust: the WHIP Input fixes are consolidated (#957), with many follow-ups on sessions, slots and teardown, and the WHEP player recovers from a brief ICE drop (#1047).
• Vision mixer performance: idle FX slots in passthrough, no re-upload of unchanged overlays, cheaper meters and borders (#1003–#1007).
• Logins survive a restart: the login cookie is now signed (#947).

Thank you, @wagenet, for ten merged pull requests in this release, for the WHIP Input fixes consolidated in #957 (#759, #787, #893, #901, #943), for the stinger groundwork in #755, and for all the testing on real rigs. It made this release a lot better.
