Add Shadow credentials module !

[qu35t-code]

Description

This PR introduces the shadow-creds module, which leverages modification of the LDAP attribute msDS-CredentialLink on a target user in order to retrieve its authentication PFX certificate.
The module is based on pywhisker by ShutdownRepo (Aka Charlie le king) and comes with options for customizing the PFX password and output directory.

Options

Common errors (examples)

• TARGET is required

• No permissions to modify msDS-KeyCredentialLink on the target (INSUFF_ACCESS_RIGHTS)

• Invalid account in LDAP

Valid examples

• With valid permissions

• Authentication with exported PFX works

• NT_HASH authentication supported

• Custom PFX password

• Custom Outdir

• I have ran Ruff against my changes (via poetry: poetry run python -m ruff check . --preview, use --fix to automatically fix what it can)
• I have added or updated the tests/e2e_commands.txt file if necessary (new modules or features are required to be added to the e2e tests)
• New and existing e2e tests pass locally with my changes
• If reliant on changes of third party dependencies, such as Impacket, dploot, lsassy, etc, I have linked the relevant PRs in those projects
• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation (WIP...)
