`go install` adds `xls2csv` not `xlsxsql`

Thank you for providing redundant releases: https://github.com/noborus/xlsxsql/releases/download/v0.4.0/xlsxsql_0.4.0_linux_arm64.rpm was an easy-to-install working fallback for me.

Thanks for the report. You were right.
I update the README to include Linux package install instructions from Releases (deb/rpm).
I have opened a fix pull request: #22.
