mm^2 to AWG conversion is wrong defined

[NoTwixD]

orginal source wv_helper.py in master branch is

awg_equiv_table = {
"0.09": "28",
"0.14": "26",
"0.25": "24",
"0.34": "22",
"0.5": "21",
"0.75": "20",
"1": "18",
"1.5": "16",
"2.5": "14",
"4": "12",
"6": "10",
"10": "8",
"16": "6",
"25": "4",
"35": "2",
"50": "1",
}

as we know its wrong becouse 0.5mm^2 is not 21 awg
also 0.34mm^2 was adjusted to easy to buy 0.35mm^2 that is only aviable size in metrics, the same to awg 21 , 0.4mm^2 and its not 0.5mm^2
the same for awg 20 as its not 0.75 , add awg 17 as its true 1mm^2

it should be :

awg_equiv_table = {
"0.05": "30",
"0.08": "28",
"0.10": "27",
"0.14": "26",
"0.25": "24",
"0.35": "22",
"0.4": "21",
"0.5": "20",
"0.75": "18",
"1": "17",
"1.5": "16",
"2.5": "14",
"4": "12",
"6": "10",
"10": "8",
"16": "6",
"25": "4",
"35": "2",
"50": "1",
}
