Format long member binding and constructors according to the F# style guide

[nojaf]

Fixes #868.
Notice that not everything is possible to adhere to the max page width.
For example:

type Foo =
    static member Deserialize(loooooooooooooooooooooooooooooooooooooooooooooooooooooonnnnnnnnnnnnnnnnnnnnngggggggggggJsonVaaaaalueeeeeeeeeeeeeeee): SomeType =
        Decode.SomeType
            loooooooooooooooooooooooooooooooooooooooooooooooooooooonnnnnnnnnnnnnnnnnnnnngggggggggggJsonVaaaaalueeeeeeeeeeeeeeee

I think this is an acceptable trade-off for now. I'm open to discussing this though.

How about:

type Foo =
    static member Deserialize(loooooooooooooooooooooooooooooooooooooooooooooooooooooonnnnnnnnnnnnnnnnnnnnngggggggggggJsonVaaaaalueeeeeeeeeeeeeeee)
                                 : SomeType =
        Decode.SomeType
            loooooooooooooooooooooooooooooooooooooooooooooooooooooonnnnnnnnnnnnnnnnnnnnngggggggggggJsonVaaaaalueeeeeeeeeeeeeeee

Sounds reasonable, I would like it to align with the start column of the parameters.
As you can see here.
It looks slightly further in your example @knocte.
Not sure if that is just GitHub formatting.

Well, in my preference I like to indent the return type 4 spaces more (if indent=4), but I can live without that.
