The test `location_coordinates.csv` contains invalid CSV

The test currently contains the following data (see commit https://github.com/max-mapper/csv-spectrum/commit/9ed330c6947381c2771eaadd06019768e6a9179):

Contact Phone Number,Location Coordinates,Cities,Counties
2095257564,37�36'37.8"N 121�2'17.9"W,Modesto,Stanislaus

This is invalid CSV: there are two values that contain a double quote ". According to the CSV standard, these values should be enclosed in quotes and the quote itself must be escaped:

5. Each field may or may not be enclosed in double quotes (however
   some programs, such as Microsoft Excel, do not use double quotes
   at all). If fields are not enclosed with double quotes, then
   double quotes may not appear inside the fields. For example:

   "aaa","bbb","ccc" CRLF
   zzz,yyy,xxx

and:

7. If double-quotes are used to enclose fields, then a double-quote
   appearing inside a field must be escaped by preceding it with
   another double quote. For example:

   "aaa","b""bb","ccc"

Can you please adjust the test?

Open the location_coordinates.csv fixture and inspect the row quoted in the issue, using the linked RFC 4180 guidance as the reference. Correct the embedded double quotes so the fixture is valid CSV, then run the relevant repository tests to confirm the updated test data is accepted.
