GIF 89a Encoder/Decoder

omggif is a JavaScript library designed for low-level encoding and decoding of GIF 89a format images. It provides explicit `GifReader` and `GifWriter` classes that operate directly on byte buffers, typically `Uint8Array`s or Node.js `Buffer`s. This gives developers granular control over every aspect of GIF generation, including frame dimensions, color palettes, delays, and other GIF specification details. First released in 2013 and last updated to version 1.0.10 in June 2017, the package is considered abandoned and has received no further maintenance or feature updates. While historically useful for both browser and Node.js environments due to its lightweight and pure JavaScript implementation, modern projects might find it lacks contemporary features, active community support, or the high-level abstractions found in more actively maintained GIF manipulation libraries.
