lines2ss, changing coords of other mooring lines

[TheMercer]

Description

When you have Three lines. Two being purely chain and third being semi-taut (chain-nylon).

When using line2ss it changes the fairlead position of the other two lines.

Steps to reproduce issue

1. Two mooring of Chain
2. One line being semi-taut
3. Run line2ss on ms

Current behavior

Coords change

Expected behavior

Coords of other lines stay the same after change.

Fix i did so far (however i don't know how good it is)

I moved the initialisation and equilibrium in lines2ss to lines2subsytem

Which fixed this behaviour

Moorpy.helper:line 1121 & 1122 into 1120 function call

@TheMercer , please provide example input file to understand the behavior and the expected behavior?

I will get something in the week.

Make a subsystem which is made of two lines (semi taut, like chain or nylon or even just chain and chain) just something where one of the main mooring is subsystem.

Have the other two lines as just full chain and non subsystem.

When you apply lines2ss it will affect the other two lines in the system when doing the equilibrium part. Which is why I moved that part of the code
