Added an auto-fixing handler

[herosi]

When I analyzed a sample, RIFT reported an error.

2025-10-31 09:41:35,808 - INFO - Autofix failed for crate = hex, try fixing issue manually. Skipping the crate
2025-10-31 09:41:43,221 - INFO - Unknown error occurred!

The sample directly uses hex 0.4.3. And it also uses mmap 0.1.1, which also uses hex as its dependency, but uses a different version, 0.3.2.
Therefore, they are conflicted. When I compiled them manually with the command below, I got the message below.

> cargo build --release --package hex
error: There are multiple `hex` packages in your project, and the specification `hex` is ambiguous.
Please re-run this command with `-p <spec>` where `<spec>` is one of the following:
  hex@0.3.2
  hex@0.4.3

So, I implemented the error handler.
The handler adds the version number of the target crate if the error is emitted.

I also fixed typo of "occur" as well ;-)
