Update build process of filter libraries that are being patched

Some of the filter libraries built in this project use a process which patches the source of the upstream library after downloading it via CMake's FetchContent in order to try to adapt the build process to this project. This process causes issues when upstream libraries are updated and makes it difficult to move to new releases of these libraries. The build process for these filter libraries should be updated to not patch the source and instead set CMake variables as appropriate to control building of each library. The filter libraries currently being patched are:

- Blosc
- Bzip2
- JPEG
- LZF
- ZFP
- ZSTD
