[Fixed] I think /host/bandwidth [GET] in the docs meant the other way around

Was reading through https://api.sia.tech/#host-bandwidth-get and got confusion over the definition of upload and download to the host's perspective, when comparing to vnstat and the implementation of Sia Host Dashboard.

By looking at the docs it seems to mean the download == host egress and upload == host ingress, but it is the other way when looking at the actual reporting of bandwidth by the system through vnstat:

According the API, I had 141,165,984 upload < 4,667,201,978 download, which does not to tally with vnstat, where rx is ingress (I had 4+GB, closer the download reported by API), tx is egress (I had 200+MB, closer to upload reported by the API)

I also cross referenced the usage of this with the source code of Sia Host Dashboard, which it has the "Received" value, which is the host ingress, is actually taking the download property from API.
