implicit conversion warnings

[adamgreenhall]

I'm getting a lot of warning messages from simple Decode:

code:

reader, err := os.Open(fnm)
... 
img, err := goheif.Decode(reader)

setup:

$ go version
go version go1.21.4 darwin/amd64

output:

lots more of this warning ^

conversion to jpg seems to work just fine, so maybe it's just noise - but is there any way to get rid of these warnings?

also getting warnings on go build, if that helps
