Xleapp

* Added a few more helper functions:
* deep_get() - helps search dictionaries for values
* filter_strings_in_files() - removes unprintable strings from a
file

* Artifact changes
* copyfile() now accepts a :obj:`bytes` object to save. This
recommended method to save files when processing an
artifact.
* You can modify the report tile of an artifact by setting the
:attr:`self.report_title` on the artifact. The default title
is the :attr:`self.name` attribute.

* Report changes
* :func:`nav()` macro has an additional argument for the artifact
name. This helps with setting the artifacts as "active" on
their respective reports
* The device tab on the report propertly spaces out the words based
on camel case ("PhoneVersion" -> "Phone Version") when displayed
on the report.

Reports (KML, TIMELINE, HTML) files updated
* KML, TIMELINE, HTML updated/fixed
* KML report is ran if and artifact contains three fields:
"Timeline", "Latitude", "Longitude".
* At this time, these fields are checked in the "report_header"
list of headers. They must be exact but can be in any order.
* DBFile validator was simplified because it was not working as
intended
* Database Service (:obj:`DBService`) added to support managing
the :obj:`DBManager` objects.
* Added pagnation and search fields to artifact tables.
* Core artifacts will not produce HTML report files

* Version bump to 0.1.1

* Updating type hints + Minor changes

Plugins:

* Moved the "register_seekers" function. I hope this will align more
on the intent of the function

Type hints are being updated after the inital fix for iTunes

* Renamed main application class + other Changes

* The main application class "XLEAPP" renamed to a more generic
name "Application"
* web_icons.py changed to for readabilty.
* Artifact class changes
* Added `data_save_folder` property to artifact classes.
* This gives a quick reference on the export directory each
artifact should save in.
* It is recommended not to save outside this folder when exporting
data from an extraction.
* Updated `copyfile` function to use the new `data_save_folder`
property. This function provides a direct way to export data
from an artifact to the export folder. It is the preferred
method to use on an artifact to save data.

* Removed `tests\` from .gitignore

TODO: Add tests suite

* Ensure `--artifacts` as at least one value

* Minor fixes

* Fixed report naming for html files.
* Fixed artifact naming for navigation list
* Fixed process.log on how paths are outputted. Before, the file
did not show all files looked at.
* Fixed for files returned back to an artifact if several regex are
used with `return_on_first_hit` as `True`.

iTunes Backup parsing fixed

*Unenrypted* backups from iTunes can be parsed from dictionary,
zip, tar, or gz. If the file is compressed, it will be extracted
automaticaly for you. Unenrypting backups is not supported (yet).

The main sections of the application are stable.
* completely wrote application from
ileapp (https://github.com/abrignoni/iLEAPP/)
* Plugin system has been added.
*note:* artifacts still need to be moved to the new format.
Check [Creating Artifacts](https://github.com/flamusdiu/xleapp/blob/main/docs/current/artifact-creation.md) for more information.
* GUI side of the application has been reworked and extended to
support plugins as well. Check the docs for a screenshot.
* Type hints and docstrings have been added and mostly completed.
There might be dragons hiding so let me know if there needs any
slaying!
* Lots of changes and additions over the past year+.

GUI has been fixed and working. See image below for a quick look at how it work.
