Reading a pfs file with embedded string, e.g. 'hello ''to'' the world'

[ecomodeller]

Describe the bug
Reading a pfs file with embedded strings changes the formatting to a format not accepted by Mike Zero

To Reproduce
Example text:

[ECOLAB_MODULE]
    [DERIVED_VARIABLES]
        [DERIVED_VARIABLE_106]
            Touched = 0
            name = 'alfa_PC_T'
            type = 0
            dimension = 3
            description = 'alfa_PC_T, ''light'' adjusted alfa_PC, ugC/gC*m2/uE'
            EUM_type = 999
            EUM_unit = 0
            unit = 'ugC/gC*m2/uE'
            ID = 597
        EndSect  // DERIVED_VARIABLE_106
    EndSect
EndSect

>>> import mikeio
>>> mikeio.__version__
'1.2.0'
>>> pfs = mikeio.read_pfs("tiny.m3fm")
>>> pfs.write("tiny_out.m3fm")

Expected behavior
