this line in geo.rs let lambda0 = (((z - 1) * 6 - 180 + 3) as f64).to_radians(); fails for all UTM zones < 31

it should be let lambda0 = (((z as i32 - 1) * 6 - 180 + 3) as f64).to_radians(); or zone could be i32

Are there any plans to support these conversions?

Hi there,

Thanks for making this crate! Would you be open to supporting f32's as well as just f64?

ie: https://docs.rs/coord_transforms/1.3.0/coord_transforms/d2/fn.cartesian2polar.html is hardcoded for f64.

Right now I'm doing a bunch of unnecessary casts because my engine uses f32's atm. I'm still learning rust, but if your knowledgeable about a good method for doing so (maybe something like rust's Into trait?) I would be happy to put together a PR, if your open to merging/discussing it.

Thanks!
