Fix for ansys cdb file fragility.
Doc updates.
Added logo test files, that make a colour distribution similar to the LUMA logo.

Proposed changes

1. This pull request has important fixes for the ANSYS cdb file reader that prevent node read errors from a fragile set of if statements that compare part lengths that could not really capture all arrangements sensibly.

   • This solution simplifies and uses the already existing function that parses scientific values.
   • This closes Ansys reader fails when node value is not spaced #4

2. Documentation has had slight readability updates.

3. A public test has been added that allows the LUMA logo to be generated by the software.
