[FEATURE] Read from stdin, encrypt/decrypt to stdout.

[barkoder]

Is your feature request related to a problem? Please describe.
As of 8.8.1 , dexios only reads from a file.
There is no way to pipe a file to dexios and have it process the file.

Describe the solution you'd like
A new option to allow reading from stdin.
Another option to allow printing to stdout.

Describe alternatives you've considered
dexios -e -k keyfile --aes --argon test.file - | <SOMETHING ELSE>
Doesn't work.

dexios -e -k keyfile --aes --argon test.file test.file.enc
cat test.file.enc | dexios -d -k keyfile -
Also doesn't work.

Thank you @brxken128 for dexios.
