- Returns a vector of dynamic entries from the given fd and program headers 
- Maybe gets and returns the dynamic array with the same lifetime as the [phdrs], using the provided bias with wrapping addition.
If the bias is wrong, it will either segfault or give you incorrect values, beware 
- Given a bias and a memory address (typically for a correctly mmap’d binary in memory), returns the - _DYNAMICarray as a slice of that memory
 
- Gets the needed libraries from the - _DYNAMICarray, with the str slices lifetime tied to the dynamic array/strtab’s lifetime(s)
