Update to RKM if ngbehavior=lt is set:
Reading C and R values follow the RKM convention with 2 exceptions:
Upper case and lower case letters are not distinguished.
Letters m, M denote milli (1e-3), letters Meg or meg denote 1e6.

Enable RKM notation for R and C, when ngbehavior LT is selected.
Add 2 evaluation functions specific for R and C respectively.
R has code letters L, R, K, M, G, T enabled. M here is Meg!
C has code letters p, n, u or µ, m, F. F here is unity, femto is
not available, m is still milli!
Two examples files show all cases.

Add new SOA parameters (safe operating area) for BJT.
We now scan for max of Ic, Ib, power, taking into
account the max allowed temperature, using the thermal
resistance rth0 model parameter between juntion and ambient.
Two user options are there: If rth0 is given, we calculate
a derating of the max power allowed.
Without a constant max power according to model param pow_max
is assumed.
The new model parameters for the bipolar model are:
pow_max, ic_max, ib_max, te_max, and rth0, in addition
to the already existing vbe_max, vbc_max, adn vce_max.
