Add fet custom pattern

[LuighiV]

Add possibility to create any patter with an array of fets and do an automatic routing.

Based on custom patterning implemented for #50

Note: If required we can remove commits from BJT just to enclose for custom pattern

line 623 of [469b72e], We are taking the base geometry for the new emitter port. This could cause layer/port mismatch.

Hi @Nimok15, thanks for reviewing it. I've checked it and, indeed, it is using the base port as reference. I don't think it will have an issue with routing because the destination will move it to an absolute position, and layers are the same for all of them. However, I agree that it's not clean and is better using the right reference for the emitter. Thanks for noticing.

By the way, I couldn't see your suggested change in the code itself, but I know what you meant and going to update the branch with a fix.

Thanks,
Luighi

Hi @Nimok15
I think I've added the requested change, can you take a look on it please?
As this PR is built on PR #50 I've added the correction to both.

Thanks,

Hi @LuighiV, thanks for updating it. I will review #50 and get back to you.

Thanks,

Can you review and add a CI check?

Hi Prof. @msaligane

I've added the checks and seems that is passing. However, maybe it is good to add more for the extra features I'm including here. I'll work on this during the week.

Thanks,
Luighi
