Original Pull Request: https://github.com/adamhathcock/sharpcompress/pull/898

State: closed
Merged: Yes

Similar to #897, this improves performance and reduces memory allocations when reading certain 7-zip files.

Using the .7z file from https://github.com/adamhathcock/sharpcompress/issues/399#issuecomment-405028725, I measured a speedup in reading / skipping the entire .7z file from ~23 seconds to ~18 seconds, and memory allocations dropped by ~8.5GB.
