relecov schema: Major changes

[ESapenaVentura]

Description of the issue

We want to apply the following major changes to the schema:

• Add the keyword unevaluatedProperties to the root of the schemas we generate so that no extra properties are allowed.
• To avoid getting fields with empty strings (e.g. {'sequencing_sample_id': ''}), add a minLength to the options for the properties.
• snake_case all properties when possible (enforce style, but don't break the existing database)
• Add dependentRequired rule to enforce the main property when an if_x_other_specify is present
• Add rules to enforce if other value, then explaining property must be set

Action Items

• Change build.py so that it generates the schemas with the keyword unevaluatedProperties and sets it to false
• Add the parameter to the option column
• snake_case the properties in the excel template
• Add column in excel template depends_on
• Update build.py to pick on new depends_on column to generate dependent fields
• Add enums for properties that should have it in the excel file
• Build new schema, upgrading to 4.0.0 (Major changes)
• Merge PR with changes
