Create a new script to extract
- ELF header
- Program header table (PHT)
- A given segment number
- Hash table segment with type as NULL and p_flags as 0x02000000
from an ELF.
Usage:
```
elf_segment_extractor.py [--eh] [--pht] [--segment <index>] [--hashtable] <elf_file> <output_file>
```
BUG=b:419213272
TEST=Extract first segment alongwith ELF header and PHT.
TEST=Extract a segment with an index number.
TEST=Extract the last segment if index is 'N'.
TEST=Extract hash table segment alongwith ELF header and PHT.
e.g.
elf_segment_extractor.py --eh --pht --segment 0 cpucp.elf cpucp_meta
elf_segment_extractor.py --segment 0 cpucp.elf cpucp_meta
elf_segment_extractor.py --segment N cpucp.elf cpucp_meta
elf_segment_extractor.py --eh --pht --hashtable cpucp.elf cpucp_meta
