Infinite loop in deflate::compress_to_vec() on empty or one-byte slices

[Vlad-Shcherbina]

To reproduce, run the following program (with miniz_oxide 0.3.6):

fn main() {
    miniz_oxide::deflate::compress_to_vec(&[], 6);
}

Expected result: it should terminate instantly.
Actual result: it does not terminate.

Same for

fn main() {
    miniz_oxide::deflate::compress_to_vec(&[0], 6);
}

Ah somehow missed this issue being posted, will look into it.

Hey I just also hit this bug. Can we get a minor patch release to the crate so the fix is on crates.io?

[oyvindln]

Yeah, was hoping to get the fix for #74 as well, but haven't got confirmation on it yet.
