Implement stdin input if a file is not specified in command line.

In documentation there is an example that says read 32 bytes but image shows it reads 16

Implement the M and K units to comprise 1024 * 1024 and 1024 patterns.

Update cargo toml version to 0.3.3

Remove dots from cli txt documentation as clap doesnt follow this pattern.

There are too much unwrap without proper error handling causing execution error prone, like the one in main function.

Enhance documentation to fit the cli new features.

Update the documentation to fit version 0.3.0.

Consider using a buffer instead of using print! macro to perform output, because print! will flush the buffer all time degrading performance.

Skip empty data offsets when parsing the entire file, There is no need to print the entire file and its missing data.

Seria melhor distinguir 0x00 de 0xff.

Enhance the error messages by translate them to human readable ones.

Update version number to milestone 0.3.0

There are a typo in the mhv usage last line. Print versio. Must be changed for print version.

Enhance characters to better visualization. Another different characters, print 0x00 as 00 and 0xff as FF, and use in left panel more diferse characters.

Update software version number for the new milestone.

Enhance documentation by add a diagram about stream workflow for better project clarity.

Consider use https://github.com/jam1garner/owo-colors, which dont allocate, to enhance performance.

The pipe separator is unecessary. Considir removing this character, leaving only spaces.

Refactor display_data function to better fit unit tests. Consider use dependency injection.

The stream diagram has an error in arrow pointing to the wrong direction (for data). Must point to read data process.

Seems that struct, cli error was forget in main. Remove it from main.rs.

Update documentation to fit new version

Implement units for hexadecimal input, that could be useful to search by offsets.

Missing coma on doc usage help near mb and M.

Sometimes is usefull to pass a different unit in input to save too much characters like:
