Fix airr_mod being ignored by pl.repertoire_overlap()

[frieseneggerf]

Hello, I noticed that pl.repertoire_overlap() ignores the "airr_mod" keyword.
The problem appears to be fixed by passing "params" instead of "adata" during the implicit call of tl.repertoire_overlap().

• CHANGELOG.md updated
• Tests added (For bug fixes or new features)
• Tutorial updated (if necessary)
