CQL2 Support names with ":" and other special characters

[Konkrad]

Hello,
I want to use the CQL2 function with properties which have a namespace like seen in the STAC properties extension.

func TestDebug(t *testing.T) {
	checkCQL(t, `"eo:grid" = 'MGRS-01GBQ'`, `"eo:grid" = 'MGRS-01GBQ'`)
}

Gives the error

CQL syntax error: " !!>> "eo:grid" = 'MGRS-01GBQ'"

This is an oversight in the definition used for CQL identifiers. I'll fix that soon.

What other special characters do you need?

The OGC CQL spec allows a lot of symbols in identifiers. Not sure it's necessary to support all of that?

Thank you for your very quick response. I had a look at some common STAC properties and next to [a-z] I would need ":" and "_". I created a MR. Feel free to have a look.
