Corrected csvy model files

[antreev-brar]

This PR aims to correct the csvy files csvy_full.csvy and csvy_full_rad.csvy

Description

Changes made to the code are:

• Introduced the line model_isotope_time_0: 0 day in .csvy files

Motivation and Context

When tardis model is simulated using the csvy format file examples provided in repository, it gives an error. In the tardis/io/schemas/csvy_model.yml , it's description states:

model_isotope_time_0:
type: quantity
description: Initial time for isotope decay. Set to 0 for no isotopes.

Also, various other csvy files in the repository like tardis/tardis/model/tests/data/exponential_csvy.csvy and tardis/tardis/model/tests/data/uniform_csvy.csvy have these corrections.
