This commit gives the frame-step command the ability to accept an additional argument specifying the amount of frames (forwards or backwards) to step through. By default, it steps forward 1. The frame-back-step command is reworked to simply be a call to frame-step with a -1 value. In the case where the value is exactly 1, mpv will play exactly 1 frame and stop like before. However if a backwards step is requested or multiple frames forward, then mpv will perform a very exact seek. This working well, of course, depends on the pts values in the stream being reliable which may not be the case. As a minor note, MPSEEK_BACKSTEP is renamed to MPSEEK_FRAMESTEP since forward seeks use this as well. Fixes mpv-player#10128.

This commit gives the frame-step command the ability to accept an additional argument specifying the amount of frames (forwards or backwards) to step through. By default, it steps forward 1. The frame-back-step command is reworked to simply be a call to frame-step with a -1 value. An additional flag is added that controls how exactly mpv steps through frames. By default, "play" is used which behaves like before. mpv will play through the requested amount of frames before stopping. This is more robust and reliable but could also take much longer if a high amount of frames is requested to be skipped through. This mode only works if mpv is skipping frames forward. Otherwise, the "seek" flag is used which performs a very exact seek. This working well, depends on pts values being reliable which may not always be the case. Frame skipping like this is more of a guess and should be less accurate. As a minor note, MPSEEK_BACKSTEP is renamed to MPSEEK_FRAMESTEP since forward seeks can use this as well. Fixes mpv-player#10128.

Previously, the default behavior of frame-step and frame-back-step is to play forward 1 frame or seek back 1 frame. We keep this behavior but introduce additional flags to control the exact behavior of the frame stepping. The first argument simply specifies how many frames to go through. The second argument specifies whether to play video to step through frames or to seek to step through frames. Playing through the video to step through frames only works going forwards (otherwise it will always seek). In theory we could use backwards playback for this, but that can be decided later. As a minor note, MPSEEK_BACKSTEP is renamed to MPSEEK_FRAMESTEP since forward seeks can use this as well. Fixes mpv-player#10128.
