Feature Request - Import tir data

[j-antunes]

It would be nice if OpenTire is also able to read tire data. We should create a utility function that reads the data file and saves it in a class.
I think the class should be something like:

• TireReader
  • tire_data

In this case, tire_data would also be a class. This class would contain the information of each column in the data file.
I would create tire_data as follows:

• data
• unit
• name

And have the following functions:

• import tire data
• export tire data
• print header
• plot data
