Native Float16Array support

[zakjan]

Currently, Float16 GeoTIFF files are returned as Float32Array.

Native Float16Array is becoming widely adopted this year https://caniuse.com/mdn-javascript_builtins_float16array

What are the necessary steps in this library to add this support?

• drop @petamoriken/float16 dependency
• use Float16Array at https://github.com/geotiffjs/geotiff.js/blob/master/src/geotiffimage.js#L67 and related places
• anything else?

I think that is what would be required, yes. Would you like to open a PR for that?

@constantinius Sure, here it is #478

The test pass with the new test file. Although I'm not happy about the eslint supressions
