vf_yadif: switch to option parser, allow disabling by default

Browse Source 
Use the option parser instead of sscanf. Remove the parameter changing
the field dominance (it has been marked deprecated for ages). Add a new
suboption "enabled", which can be used to disable the filter by default,
until it's enabled at runtime:

    mpv -vf yadif=enabled=no

Operates like tfields.
*NOTE*: This option will possibly be removed in a future version. Use

:yes: Filter is active (default).
:no: Filter is not active, but can be deactivated with the ``D`` key
