Supporting enter key on numeric pad.

[ruimo]

Is your feature request related to a problem? Please describe.
No, this is not related to any problems.

Describe the solution you'd like
eframe::egui::Key::Enter does not fire if enter key on numeric pad is pressed. Add eframe::egui::Key::NumEnter that is fired if enter key on numeric pad is hit.

Describe alternatives you've considered
Firing eframe::egui::Key::Enter when enter key on numeric pad too can be an alternative (does not add new event code).

Additional context
None.

Preferably you would have:

• AnyEnter
• NumEnter
• Enter

that makes the most sense for modifiers as well (Any, Left, Right)

Hi @emilk. Thanks for your work on egui. Are you interested in getting a PR for supporting NumEnter (enter from numpad)? If so, can you please share your thoughts on how you would prefer it work? Are you ok with a new Key::NumEnter?
Right now there is no easy way to work around this issue, as far as I understand.
Thanks.

I'd like to vote for this issue. In my case, I expect my user to type in numbers and therefore to prefer to use the keypad Enter rather than the regular Enter.

I think adding a Key::NumpadEnter makes sense, and then also check for that wherever we currently check for Key::Enter

AnyEnter would be nice to have too, like mentioned above.
