Compression is optional only in v2 paste format.
Currently available types: 'zlib' and 'none'.
To set compression use `-c "none"` or `--compression "none".
When receiving paste, compression detected from 'adata' field
Now text is taken if no `--notext (-q)` argument is passed.
If that flag used, paste will be created with empty text,
but file for send must be specified
If `notext` arg is not used, text will be taken in next order:
* from `--text (-t)` argument
* from stdin (forcibly)
Here's no ability create paste without any text.
