Overwrite labels

[nbara]

Hi, thanks a ton for this nifty package !

It'd be useful if we could overwrite the individual bar labels.

echo "Label,3,9,1" | termgraph --custom-tick "😀" --no-label  --row-values {three, nine, whatever}

Would output:

😀😀😀 three
😀😀😀😀😀😀😀😀😀 nine
😀 whatever

Alternatively, one could provide custom suffixes for each row (currently one can only append a single suffix to all rows).

This would be doubly cool if there was a way to automatically convert the labels into human readable format. EG: 13659757713600 bytes shows a label like 13.6T
