[Feature] Implement Linux's hexdump command features into Hexdump

[ZackeryRSmith]

[Feature]

Feature Suggestion

Hexdump doesn't currently implement all features from the linux built-in hexdump utility command. As such Hexdump isn't currently a replacement for the hexdump command. Until Hexdump has these features Hexdump can't be concidered a viable replacement for the built-in one.

Use Case

If a end-user want's to use Hexdump as a replacement for the built-in, they would lack features that the original had. Which in their use case may just be the decision of using Hexdump or sticking with the old one.

Your Environment

• Operating System: Arch Linux x86_64 (running linux kernel 6.1.38-1-lts)
• Project Version/Commit: v1.0.2

@ZackeryRSmith Can you add a list of all the features that the original Hexdump provides?

output taken directly from hexdump --help for more indepth info on each feature I'd check man hexdump

 -d, --two-bytes-decimal   two-byte decimal display
 -o, --two-bytes-octal     two-byte octal display
 -x, --two-bytes-hex       two-byte hexadecimal display
 -L, --color[=<mode>]      interpret color formatting specifiers
                             colors are enabled by default
 -e, --format <format>     format string to be used for displaying data

--color will be handled with a config, instead of an argument --no-squeezing will be flipped. squeezing is disabled by default and you turn it on with --squeezing Because I have no clue how they work, I will not be implementing the format strings. I might add them in a later version if I ever figure out how they work the two-byte format options will be added in a minor version after there is a stable zig release -C (--canonical) will be replaced with a --one-byte-hex option and an --ascii option
