[General] Release `v1.0`

[ocots]

Before we release the version v1.0, we need to complete the following tasks.

• Add problems compatible with ExaModels. See [Dev] Adding models for exa #88.
• Update the unit tests and the documentation accordingly.
• Review the descriptions of the problems. See [General] Review the documentation of the problems #110. We need to review the mathematical description of each problem (in ext/Descriptions directory) and check the validity of the associated references.

Note

In the future, we should add some problems (#92): MRI, Kepler, and some that we can find in Betts book second edition.
