ModDetectedDefault config annotation

[Lyfts]

Inspired by #26

This lovely test config https://github.com/GTNewHorizons/GTNHLib/blob/55582cbe9ba1c4cf6d22a4c904e5259a051a0c8a/src/main/java/com/gtnewhorizon/gtnhlib/config/TestConfig.java does correctly get parsed into the following while Hodgepodge is present

test {
    #  [default: false]
    B:testBoolean=false

    #  [default: true]
    B:testBooleanButCooler=true

    #  [range: 4.9E-324 ~ 1.7976931348623157E308, default: 3333.0]
    D:testDouble=3333.0

    #  [range: 4.9E-324 ~ 1.7976931348623157E308, default: 1.0]
    D:testDoubleButCooler=1.0

    # This is a test double list [default: [4.0, 5.0, 6.0]]
    D:testDoubleList <
        4.0
        5.0
        6.0
     >

    # This is a test double list (or not) [default: [1.0, 2.0, 3.0]]
    D:testDoubleListButCooler <
        1.0

        3.0
     >

    # 
    # Possible values: [TEST1, TEST2, TEST3]
    #  [default: TEST2]
    S:testEnum=TEST2

    # 
    # Possible values: [TEST1, TEST2, TEST3]
    #  [default: TEST1]
    S:testEnumButCooler=TEST1

    #  [range: 1.4E-45 ~ 3.4028235E38, default: 3333.0]
    S:testFloat=3333.0

    #  [range: 1.4E-45 ~ 3.4028235E38, default: 1.0]
    S:testFloatButCooler=1.0

    #  [range: -2147483648 ~ 2147483647, default: 3333]
    I:testInt=3333

    #  [range: -2147483648 ~ 2147483647, default: 1]
    I:testIntButCooler=1

    # This is a test int list [default: [4, 5, 6]]
    I:testIntList <
        4
        5
        6
     >

    # This is a test int list [default: [1, 2, 3]]
    I:testIntListButCooler <
        1
        2
        3
     >

    #  [default: STRING]
    S:testString=STRING

    #  [default: STRING]
    S:testStringButCooler=STRING

    # This is a test string list [default: [test4], [test5], [test6]]
    S:testStringList <
        test4
        test5
        test6
     >

    # This is a test string list (or not) [default: [test1], [test2], [test3]]
    S:testStringListButCooler <
        test1
        test2
        test3
     >
}

I also added a ModDetectedDefaultList which accepts multiple ModDetectedDefaults in case several defaults are desired for different mods, it will always use the value of the first mod it finds in the list.

Great work!
What is the purpose of the `@SneakyThrow`s?

[Lyfts]

I found it exceptionally annoying to read through the parsers with the very large amount of exceptions that had to be added to the various methods throws declaration.
The Exceptions that can be thrown doesn't really matter here as all caught exceptions are repackaged into a ConfigException that describes which field it failed at along with the original exception.

[Caedis]

Gotcha, so it basically fakes the throws list for the compiler
