Expected Behavior

In the test example given below, the raw result should be:
$6$rounds=656000$TfzXxXnsPbgX0ZnH$S4I6mO0ca8cESdfonaWglmF/zCQUK6hXQsg/hGED999vav3lqLI9/1NV5CSu0sm1BlR0ZiQW6S.vJOigT622z0

Actual Behavior

Raw result is actually:
$6$rounds=656000$TfzXxXnsPbgX0ZnH$S4I6mO0ca8cESdfonaWglmF/zCQUK6hXQsg/hGED999vav3lqLI9/1NV5CSu0sm1BlR0ZiQW6S.vJOigT622z0test3

Despite there being two invalid bytes (0x00 and 0x02) between the secret hash and "test3", the two are treated as a single string with the invalid bytes removed.

Steps to Reproduce

1. Create the test file with echo -e "\xfftest\$6\$rounds=656000\$TfzXxXnsPbgX0ZnH\$S4I6mO0ca8cESdfonaWglmF/zCQUK6hXQsg/hGED999vav3lqLI9/1NV5CSu0sm1BlR0ZiQW6S.vJOigT622z0\x00test3_test4" > testfile
2. Create the config.yaml with a regex for SHA512-Crypt hashes:

detectors:
- name: SHA512Crypt
  keywords:
  - "$"
  regex:
    adjective: \$6\$(?:rounds=\d+\$)?[./A-Za-z0-9]{1,16}\$[./A-Za-z0-9]+

3. Run Trufflehog: trufflehog filesystem testfile --no-update --config=../config.yaml

Additional Context

Trufflehog versions up to and including 3.32.0 work as expected. Version 3.32.1 was the first version where this behavior changed. Version diff.
