Dmitry Isaenko
610aa5dd96 1. Start moving to 'InFileStreamProducer' entity to simplify work with [inside-NCA]-[in-pfs0/romfs]-[sub-files] that could be located inside encrypted or not encrypted sections. This approach will allow us to map filesystem to/as 'enough-informed' objects that could perform actions on content without pre-extraction. For example decompress NSO0 'ELF' sections from the inside PFS0 that is located inside NCA3 that is located inside XCI/NSP. 
2. Add NSO0 support. Add NSO0 decompressor/extractor
3. Add logo draft sketch, update dependencies, add LZ4 libs deps, add final identifier in some places
