Add go-ole to go.mod

[saedx1]

Hi,

First of all, thanks for this library, it's been a huge help for us over the last couple of months.

• I created this PR to update the go.mod using go mod tidy.
• Importing this package leads to having go-ole as an indirect dependency in the go.mod of the importing project.
• This comes as a result of odbc not having go-ole in it's go.mod.

I'm aware go-ole is only used for testing here, but I feel it belongs more to this go.mod than the go.mods of the importing packages.

Thanks

I don't use go modules myself, so I will take your word for it.

Thank you for doing it.
