[BUG] - Bug in the excel config file

[mcampos16]

Describe the bug
When adding a new benchmark to JADE, if the name of an excel sheet defined in the excel config file is too long, an error is raised.
An example has been added to the screenshots section.

To Reproduce
Steps to reproduce the behavior:

1. Create an excel config file.
2. Define a long name for an excel sheet.
3. Run the corresponding benchmark's prost-processing.

Expected behavior
I expected to either:

• Get a warning/descriptive error that informs you that the chosen name is too long.
• Run the post-processing of the benchmark smoothly independently from the length of the excel sheet's name.

Screenshots
An excel config file that causes the error to be raised, with the name causing the problem highlighted:

The error being raised:

The "corrected" excel config file (this one doesn't raise an error and the excel processing runs smoothly):
