Flag "-dynamic" to run a query without type checking

[philrz]

The docs currently speak of a -dynamic flag to run a query without type checking data from the source, but this flag has not yet been implemented. Therefore we'll either want to implement this before a GA release or update the docs.

I'm not 100% certain, but based on a recent group discussion I think this flag may be helpful for allowing us to add a test as discussed at #6356 (comment), so this comment is a note-to-self to revive that topic when we add this functionality.

Verified in super commit 97f5f6c.

For example, before the merge of #6434, type checking was not performed for data read from SUP format files. Therefore a typo in an attempt to reference a field by name would give an error("missing") like shown here.

$ super -version
Version: 1699162e1

$ echo '{foo:"bar"}' > data.sup &&
  super -c "values fo" data.sup
error("missing")

The changes in #6434 enables type checking in formats like this by default, therefore on that same operation the user is now shown a helpful error message to alert them to their typo.

$ super -version
Version: 97f5f6c5d

$ super -c "values fo" data.sup
no such field "fo" at line 1, column 8:
values fo
       ~~

Now if for some reason the prior dynamic behavior is desired, the -dynamic flag is available.

$ super -dynamic -c "values fo" data.sup
error("missing")

Also, regarding the test mentioned in #6385 (comment), @nwt confirms this was added here.

Thanks @nwt!
