Remove vertical edges when interpolating and make some other improvements:
do not calculate a polynomial approximation for unused frames;
center the target x-value in the frame; and do not propogate a reduction
in degree to later frames.

analog time-step.

In dctran.c, call EVTcall_hybrids() (which then calls a subset of

code model instances) only when the current timestep was successful.
That is efficient and means that code models may rely on such calls,
for example a co-simulator may safely advance to the end of the timestep.
The function cm_irreversible() that is mentioned in a comment will be
added in a later commit.

Add a predifined variable 'skywaterpdk' to speed up circuit

loading and parsing.
If set, it removes quoting tokens for params. This requires
that Skywater PDK does adequately stick to the ngspice syntax
to put params in between braces. As far as tests go, it does.
It also set the number of nodes for MSO devices to 4, so no lengthy
search is required.

KLU is selected by 'option klu'
If both 'option klu' and 'option sparse' are given,

'option sparse=0' de-selects spares, i.e. selects klu.

'option klu=1' has the same meaning as 'option klu'.
