…attern selection popup when pattern is already open
This PR does two things. Most importantly, it fixes a segfault that can
be caused by opening a recent file with pattern sync enabled.
Secondly, it makes it so that the pattern selection popup does not
appear if you already have text in the pattern editor for a given
provider (due to CLI args, a project file, pattern sync, etc.). If you
open a file normally, that text field is empty and the popup will appear
so you can select a pre-made pattern like usual.
The current CLI argument parsing did not work as documented and had a
number of issues related to multi-flag (subcommand) parsing. I've
reworked the logic in such a way that should maintain full compatibility
with any existing scripts/use-cases but with added functionality.

Add block list for intel hex and motorola srec
TEST: Load various hex and srec files
- Test search capability
- Test jump to section
### Problem description
The intel-hex/motorola formats can be loaded but not quite ideally,
including there is no list of segments/blocks that
can be extracted from file layout (metadata).
### Implementation description
I implemented similar feature as process monitor provider does, to
extract chunks while parsing the file and show
them as a sidebar list
### Screenshots
Looks like this:

### Additional things
There are some improvements that could be made:
1. There is currently no API to jump to address, which would be useful
to jump to beginning of a hex/srec segment.
2. When jumping with setSelection, jumping backwards makes the first
visible line the jump address/line, however, when jumping forward, the
jump address is at the bottom (see image).
3. Unsure about convention for searches, should we search elements as
startsWith given user string, or contains or including 0x prefix or not,
whether to keep prefix zeros since the region size is 8 bytes, but
addresses should be <= 32 bits, etc.
Editor was attempting to delete non-existent chars which is UB. Fixed by
checking before deleting. Also fixed was a problem created by having to
press enter to change the search string which advanced the selection to
the first match. In the next step one would expect that pressing enter
on the replace field would replace the selected item but was replacing
the item found after he first.
This was fixed by always replacing the current selection first. If the
replacement is the same as the searched term then replacing won't
advance the cursor, but if they are different then the current match
will no longer exist so it would search fora new one.
Fixed by only processing text that's visible.
Also fixed the cursor jumping to breakpoint line when selected by
clicking the line number and added highlighting of the current editing
line. An optimization that caches the number of utf-8 chars in each line
was included as well.
Finally, an error that caused ImHex to crash if a pattern was saved as
itself was also fixed.
