feature request: read bitmap file from ArrayBuffer, for browsers

[trusktr]

I'm perusing for tools to read bitmap file content, and stumbled on this. Neat!

In the web, reading a bitmap file can yield an ArrayBuffer with the binary data, like this:

const response = await fetch('/path/to/file.bmp')
const data = response.arrayBuffer()

I've no experience with bitmaps (other than starting to peruse how to read the data just now). I've tried steps in this guide with no luck: https://www.i-programmer.info/projects/36-web/6234-reading-a-bmp-file-in-javascript.html

But when I send the data to the GPU (WebGL), I get a black texture, so I'm doing something wrong somewhere.

Anyway, it'd be neat if this lib would detect a browser environment, and in that case either accept an ArrayBuffer object, or a URL and fetch it to an ArrayBuffer, and finally create the same sort of meta object with the same content (but ArrayBuffers or UInt8Arrays inside the object instead of Buffers).
