Problems with cyclic patches

[FranzBangar]

Description

A completely legit mesh fails when creating cyclic patches; turns out
A discord user

What To Do

Increase precision of output in vector_format in constants.py (workaround and a possible bugfix in next release)

def vector_format(vector) -> str:
    """Output for point/vertex definitions"""
    return f"({vector[0]:.15f} {vector[1]:.15f} {vector[2]:.15f})"

Beware

Make sure this doesn't break something else; if not really necessary, don't use that precision as it will clutter blockMeshDict considerably.
