Is your feature request related to a problem? Please describe.
Pixie OTel export uses an older version of the Span proto. See, e.g., the following:

  1. Example Pixie source code using older library_spans.

  2. Diff in OTel repository showing deprecation of the same.

IIUC Pixie currently uses OTel proto v0.10.0. The latest OTel proto release is now v1.1.0.

OTel proto v0.19.0 introduced a change where library_spans were completely rm'd, see:
open-telemetry/opentelemetry-proto@v0.18.0...v0.19.0

Describe the solution you'd like
Upgrade Pixie OTel proto to v1.1.0 or to either of v0.18.0 or v0.19.0. Switch to using (e.g.) scope_spans.

Describe alternatives you've considered
As an alternative, we could keep using the older OTel proto version (i.e. do nothing).
