Feature Request: --saveRecordIds flag on texei:data:export command

[amarquard089]

Hi there,

Greate work so far, I love to use your tool, but I think it would be really cool to add a --saveRecordIds flag to the texei:data:export command.
Right now the old RecordIds are not saved in the jsons when exporting data, but i think it could be a benefit for some people (like me) to have the old Ids as well.
Since I have to handle some Ids that are just written as Strings in TextFields (and there is no possibility to make them a lookup) I have to use an additional custom field to map those oldIds to the new ones.
By having the oldRecordIds in the json as a property it would be really easy to create such a mapping.

Thanks
