Export a laygo2.object.database.Library object to Cadence Virtuoso via
skillbridge.
Parameters
----------
db: laygo2.database.Library
The library database to be exported.
filename: str, optional
The path of the intermediate skill script file.
cellname: str or List[str]
The name(s) of cell(s) to be exported.
scale: float
The scaling factor between laygo2's integer coordinats actual physical coordinates.
reset_library: bool, optional
If True, the library to export the cells is reset.
tech_library: str, optional
The name of technology library to be attached to the resetted library.
Returns
-------
str: The generated skill script.
