fails on units like "ms"
Hey @satra thanks for such a clean package!

1. I installed the dev version as described in the README
1. I ran `cmixf` from the CLI to start the program
1. I entered `1ms` which should be 1 millisecond

Traceback:

```
cmixf > 1ms
type='REAL', value='1'
type='UNITC', value='m'
type='UNITC', value='s'
sly: Syntax error at line 1, token=UNITC
