CcidTransceiver: Adjust line lengths

Browse Source 
100 characters with exceptions made for CLI commands, URIs and imports.
Some of this is existing code, but for the sake of consistency, we'll
wrap all at 100 characters.

Function arguments: when this happens, if we put the closing `)` on its
own line (like `}` in code blocks), it visually stands out better for
indicating where the function call ends.
