Update/chardet package version (issue #195)

[DarianAltF4]

Description

Please include a summary of the change and which issue is fixed or implemented. Please also include relevant motivation and context (e.g. links, docs, tickets etc.).

Updated the chardet package from version 4.0.0 to version 5.0.0 in response to issue #195. The original request sought an upgrade to version 5.2, but this would have necessitated users to have Python version 3.7, while the current documentation recommends Python 3.6 and above. Version 5.0.0 of chardet is the highest available upgrade that maintains compatibility with Python 3.6+.

Can we use 5.2.0?

[telamonian]

I opened an alternative to this PR at #230 that bumps chardet all the way up to the current version 5.2.0. This is now possible due to the fact that this project has since moved on to python>=3.8

I am going to close this in favour of #230. Please follow #230 for updates.
