[FEATURE] ✨ Customizable HTTP header name

**Is your feature request related to a problem? Please describe.**
Being able to customize the HTTP header name to avoid collision or better fit with entreprise guidelines

**Describe the solution you'd like**
When adding the service to the D.I., the `DataFiltersOptions.HttpHeaderPattern` property would be used to set up the pattern for HTTP header name

```csharp
public void Configure(IServiceCollection services)
{
services.AddDataFiltersService(options =>
{
options.HttpHeaderPattern = "my-custom-pattern"; // <-- would result in handling "x-my-custom-pattern-include" and "x-my-custom-pattern-exclude"

// Additional setup

options.Validate();
}
}
```
`options.Validate()` would throw a `InvalidDataFilterOptionsException` if the `HttpHeaderPattern` is incorrect (`null`, `string.Empty`, ... )
