CreateParser.create behaves inconsistently depending on system default encoding

[dc-stripe]

CreateParser.create takes a file path, but no option for an encoding, and so (I guess) uses the system default encoding. When the file has non-ASCII characters, as the current version does:
https://github.com/snowplow-referer-parser/referer-parser/blob/0a59810d7379ff731ccfcdeabea151e4e8b31c59/resources/referers.yml#L638
it can therefore behave inconsistently on different systems.

Library version:
1.0.0

Expected behavior:
I should be able to get the same referers.json file to work on different systems

Actual behavior:
If I use a UTF-8 encoded file on a system with a different default encoding, I get a MalformedInputException

Steps to reproduce:

Please try to be as detailed as possible so that we can reproduce and fix the issue
as quickly as possible.

1. Convert the current referers.yml file to json and save it as UTF-8
2. Pass this file path to CreateParser[IO].create on a system with a different default encoding
3. Results in

Scheduling to 1.1.0, but will make sure to include it into 1.0.1 if such release will take a place.
