There was a problem hiding this comment.
Maybe better to use strnstr here and avoid adding the \0 terminator?

@Mateyhv discovered that if one has a BN220 based on ublox-8 rather than Ublox M8N, then:
This can result in erroneously reserving channel slots that cannot be used as the device passes the HW/SW test.
See https://www.u-blox.com/sites/default/files/products/documents/u-blox8-M8_ReceiverDescrProtSpec_%28UBX-13003221%29.pdf page 5
This PR changes the test to explicitly test the version extensions for "GAL"; it may also be considered to be a corner case to far.
