/*
System memory requirement:
* It's -1 for header libraries
* It's equal to size of the data section for resources that have BIN1/BIN2 header
* For resource types that don't have BIN1/BIN2 header each resource adds 16 (0x10) bytes to the size of data section of the resource library which is the resource library file size minus 24 (0x18)
* For resources that are serializable the resource library memory requirement is smaller than the resource library file size in bytes. For resources that aren't serializable memory requirement of their resource library is bigger than the resource library file size in bytes.
