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!
With an initial Window size of 1 by 1, the program aborts during launch
on my Debian 12 (bookworm) system running the Mate Desktop environment
on X11.
The exception from X is the following:
```
$ ./imhex
[18:36:33] [INFO] [main | Main] Welcome to ImHex 1.38.0.WIP!
[18:36:33] [INFO] [main | Main] Compiled using commit master@59c6d30

```
The culprit is in `hex::init::WindowSplash::initGLFW()`, specifically
the `glfwCreateWindow` call with a window size of 1 by 1, that's the
last call in the ImHex codebase, after that it's libglfw and libX11.
The issue can be worked around by inhibiting the splash screen using the
`IMHEX_SKIP_SPLASH_SCREEN=1` environment variable, setting the window to
be a size larger than 1 by 1 also seems to resolve the situation.
My hunch is that an underflow occurs somewhere with the smaller values,
but I did no further investigation into analysing the root cause.

Above the line is the commit message.
### Problem description
See https://github.com/WerWolv/ImHex/issues/2215, which I think is the
same problem, and commit description above. Edit; I did another search
in the issues, I wouldn't be surprised if #2233 is a duplicate of the
2215 issue.
### Implementation description
Please see the commit message.
Analysis was done by setting an X11 error handler, making that throw and
running it in a debugger. This is available in this dev commit;
4a24e16a2ef100a9417e572f6b16c4a95711e94e.
### Screenshots
No apparent glitches if I make the splash window stick around with
`return std::nullopt;` in the `loop()` function. I don't know if there's
an issue at the beginning, but given that the window is set to
transparent before it is created and resized I don't expect any.
Here's a compulsory screenshot of the splash screen over an editor;

### Additional things
> Anything else you would like to say
Yes! I don't use ImHex often, but it's really useful when I do, thank
you!
Added the ui namespace and broke the main rendering function into a set
of smaller functions. Reorganized the header code separating functions
into rough groups that eventually will be in separate files.
