Allow inserting keys into Keyframe strips (which is the only type of strip that is currently implemented). Note that the data model is currently limited to a single layer, with a single infinite strip. Because of this, the strip will not be shown in any UI, as there is no way to manipulate it anyway. Note that the inserted keys are not yet evaluated, so the animation isn't visible in the 3D viewport yet. That's for an upcoming commit. For more info, see #113594.
