Group Varint Offset Encoding

• Compressed integers in blocks of 3.
• Has good compretion rate, even with outliers.
• Utilized offset encoding to store less bytes.
• Appends zeros to your data, if it can't be grouped into 3. Manually keep track of the exact amount if needed.

Usage

```rust let data: Vec = ...;

use groupvarintoffset_encoding::{ compress, decompress };

// anything that can be iteratored into u32s works fine. let compressed_data = compress(&data);

let decompresseddata = decompress(&compresseddata).to_vec(); ```
