Add arrowFunction.noNewLineBeforeFnCall option

[Ty3uK]

Resolves #107.

If set to true dprint will not format this:

[].map(() => test({
    foo: 1,
    bar: 2,
}));

to this:

[].map(() =>
    test({
        foo: 1,
        bar: 2,
    })
);

and this:

const getStyles = () => css`
    display: flex;
`;

to this:

const getStyles = () =>
    css`
    display: flex;
`;

Also, please help with naming, I'm not quite sure that noNewLineBeforeFnCall is ok 🙂
