test/cloudflare_record: Fix acceptance LOC tests

[jacobbednarz]

This updates the resourceCloudflareRecordRead function to also run the
data attribute through the transformToCloudflareDNSData function
(like the Create/Update already do) in order to correctly parse the
floats that are returned as strings.

I've opened a discussion with the Cloudflare folks on fixing this
properly (not passing the floats as strings) in the response but I
suspect that won't be a quick fix and this will need to suffice while we
are working through that.

Fixes the following CI failure

------- Stdout: -------
=== RUN   TestAccCloudflareRecord_LOC
=== PAUSE TestAccCloudflareRecord_LOC
=== CONT  TestAccCloudflareRecord_LOC
--- FAIL: TestAccCloudflareRecord_LOC (2.98s)
    testing.go:527: Step 0 error: Check failed: Check 2/4 error: cloudflare_record.foobar: Attribute 'value' expected "37 46 46.000 N 122 23 35.000 W 0m 100m 0m 0m", got "37 46 46.000 N 122 23 35.000 W 0.00m 100.00m 0.00m 0.00m"

Not a big deal, but we usually modify Changelog after merging PRs, via the GitHub UI (pencil icon). It helps us to avoid conflicts in case we merge other PRs whilst one is being reviewed.
