perf(readability): improve getClassWeight speed

Browse source 
Before

```console
$ go test -bench=.
goos: linux
goarch: arm64
pkg: miniflux.app/v2/internal/reader/readability
BenchmarkExtractContent-8   	     34	 86102474 ns/op
BenchmarkGetWeight-8        	  10573	    103045 ns/op
PASS
ok  	miniflux.app/v2/internal/reader/readability	5.409s
```

After

```console
$ go test -bench=.
goos: linux
goarch: arm64
pkg: miniflux.app/v2/internal/reader/readability
BenchmarkExtractContent-8   	     56	 83130924 ns/op
BenchmarkGetWeight-8        	 246541	     5241 ns/op
PASS
ok  	miniflux.app/v2/internal/reader/readability	6.026s
```

This should make ProcessFeedEntries marginally faster, while saving
some memory.
