> *Current behavior*
> SchemaCompatibility does not work properly when `namespace` is present.
> The following schemas are `FORWARD` compatible.
> {code}
> use avro_rs::{Schema, schema_compatibility::SchemaCompatibility};
> let schema_1 = Schema::parse_str(r#"{
>   "type": "record",
>   "name": "Statistics",
>   "fields": [
>     { "name": "succes", "type": "int" },
>     { "name": "fail", "type": "int" },
>     { "name": "time", "type": "string" },
>     { "name": "max", "type": "int", "default": 0 }
>   ]
> }#").unwrap();
> let schema_2 = Schema::parse_str(r#"{
>   "type": "record",
>   "name": "Statistics",
>   "fields": [
>     { "name": "succes", "type": "int" },
>     { "name": "fail", "type": "int" },
>     { "name": "time", "type": "string" },
>     { "name": "average", "type": "int"}
>   ]
> }#").unwrap();
> {code}
> When using `SchemaCompatibility::can_read(...)` the result is `true`:
> {code}
> assert_eq!(true, SchemaCompatibility::can_read(&schema_1, &schema_2););
> {code}
> *However*, when the `namespace` is added then the result is `false`
> {code}
> let schema_3 = Schema::parse_str(r#"{
>   "type": "record",
>   "name": "Statistics",
>   "namespace": "my.namespace"
>   "fields": [
>     { "name": "succes", "type": "int" },
>     { "name": "fail", "type": "int" },
>     { "name": "time", "type": "string" },
>     { "name": "max", "type": "int", "default": 0 }
>   ]
> }#").unwrap();
> assert_eq!(false, SchemaCompatibility::can_read(&schema_3, &schema_2););
> {code}
> *Desired behavior*
> Namespace should not affect compatibility
> *Notes*
> - My team is going to provide a PR soon to fix it
