Update Utf8String.SanitizeString, add GetParts

[Haselnussbomber]

Summary:

• Added an AllowedEntities enum for the Utf8String.SanitizeString function.
• Added Utf8String.GetParts, which extracts the different texts and payloads from a string and adds them to a vector.

---

Regarding SanitizeString:

The commonly used flags 0x27F, which I don't know where those comes from, allow the following:

• UppercaseLetters
• LowercaseLetters
• Numbers
• SpecialCharacters
• CharacterList
• NewLines
• Payloads
• Unknown9 (Chinese/Korean client specific?)

---

GetParts Example:

var str = Utf8String.FromSequence(ReadOnlySeString.FromMacroString("<string(gstr1)><string(gstr2)><bold(1)>Hello @ World<bold(0)>"));
var vector = new StdVector<Utf8StringPart>();

str->GetParts(&vector);

foreach (var part in vector)
{
    ImGui.TextUnformatted($"Payload: {new ReadOnlySeStringSpan(part.Payload.AsSpan()).ToString()}");
    ImGui.TextUnformatted($"Text: {new ReadOnlySeStringSpan(part.Text.AsSpan()).ToString()}");
    ImGui.Separator();

    part.Payload.Dtor();
    part.Text.Dtor();
}

Renamed NewLines to Unicode, which is still incorrect, but eh..
It's basically everything(?) not handled by the alphanumerical and special characters filters.
If anyone has a better suggestion, let's hear it.

Could you check a bit more into what is chucked into the unicode parts?
For instance, is it all the latin characters that is region specific?

The screenshot above was just me trying to figure out what the function allows for certain UnicodeRanges (statics in C#): https://gist.github.com/Haselnussbomber/efba876a0c6e6f5a41539dde39f0f338

Renamed Unicode to OtherCharacters.
