In addition to the release note, I have also modified the docker runfile to support elixir tests, and also updated the elixir tests to be run. Release note (bug fix): In previous PRs, drivers that do not truncate trailing zeroes for decimals in the binary format end up having inaccuracies of up to 10^4 during the decode step. In this PR, we fix the error by truncating the trailing zeroes as appropriate. This fixes known incorrect decoding cases with Postgrex in Elixir.
