lz4-ts's Issues

Uncompression failure in the library

Hello,
Recently I decided to write a usdz parser in typescript , as the file format got popular since AR popularization.
As part of project I used lz4-ts , for uncompression but the following strange issue came up.
I calculate uncompressed buffer size using calcUncompressedLen , and it works very well , actually usdc file contains the uncompressed buffer size and I use calcUncompressedLen to make sure its value is correct. But when I call uncompressBlock on the compressed data , I get 'short buffer' error. I event tried to create a buffer with very larger than expected uncompressed buffer length , but the issue remained.

Issue reproduce:
