feat: Added skipping sequences of repeating bytes (#2228)

This PR implements a neat little feature I missed - the ability to jump
to the next/previous differing byte, skipping the chunk of repeating
bytes. Very useful when you analyze a raw flash dump and want to skip
the large sections of `0x00`s/`0xFF`s.

Some implementation details worth validating:
- I wasn't sure what is the correct place to put the new menu entries
into. The possible candidates were `File -> Go to address...` and `Edit
-> Follow selection`. I chose the former, although the latter may be a
better fit since it already states that the action is related to the
selection. Overall, it may be a good moment to refine these menu entries
in general.
- I didn't add any tests since I'm not sure what is the project's policy
for those. Please let me know if I need to add some!
- I added the machine-generated translations for the new menu entries
which may be considered a questionable thing. Please let me know if
you're unhappy with those, I'll drop the commit.
 
Also, thanks for such a nice tool, I use it a lot and was glad to build
a new feature for it!
