Fix a few typos (#1797)

* Fix a few typos

the difference between the param `shal` and 
`sha1` is a big deal

* Clarify price granularity and ranges

Based off of https://github.com/prebid/prebid-server/blob/master/openrtb_ext/request.go#L92

* adding min granularity back

thanks for the fixes, but removing min from granularity -- we dropped support of that at some point last year.
