Update to egui 0.26

[rib]

This updates egui and eframe to 0.26 and also bumps the version of puffin_egui to 0.26 for consistency.

Have you tested the viewer, so that one can click scopes, zoom, etc?

ooh actually it looks like selecting frames isn't working as it should here. you can select a range of frames ok, but not click an individual frame. you can also start selecting a range of frames but release the mouse button with a single frame selected and that works to select a single frame, but just left clicking a frame doesn't work atm.

The other general interactions including panning and zooming seem to be working ok

oh, or you can long press to select - so it looks like it's related to relying on .dragged() so I guess related to this change in egui:

    Improve `Response.dragged`, `drag_started` and `clicked` (#3888)

    If a widgets sense both clicks and drags, we don't know wether or not a
    mouse press on it will be a short click or a long drag.

    With this PR, `response.dragged` and `response.drag_started` isn't true
    until we know it is a drag and not a click.
    If the widget ONLY senses drags, then we know as soon as someone presses
    on it that it is a drag.
    If it is sensitive to both clicks and drags, we don't know until the
    mouse moves a bit, or stays pressed down long enough.

    This PR also ensures that `response.clicked` and is only true for
    widgets that senses clicks.

maybe we can ensure that the frames are only sensitive to drag.

okey yeah this seems to fix it:
