Waypoints - Add WaypointTextStyle

[ItsNature]

Overview

Description:
Adds per-waypoint label/HUD overrides, beam and block-outline toggles, and show/hide controls for waypoints already sent to the client.

Changes:

• New WaypointTextStyle builder: (showText, onlyShowTextWhenLookingNear, showIcons, textIconScale, labelScale, boxPadding, boxBorders, textShadow, showDistance).
• New Waypoint builder fields: showBeam, highlightBlock, highlightBlockLineWidth
• New WaypointModule API: showWaypoint(Recipients, String) & hideWaypoint(Recipients, String).

Code Example:
Displaying a Waypoint with Text Style

public void displayWaypointWithTextStyle(Player viewer) {
    Optional<ApolloPlayer> apolloPlayerOpt = Apollo.getPlayerManager().getPlayer(viewer.getUniqueId());

    apolloPlayerOpt.ifPresent(apolloPlayer -> {
        this.waypointModule.displayWaypoint(apolloPlayer, Waypoint.builder()
            .name("POI")
            .location(ApolloBlockLocation.builder()
                .world("world")
                .x(-500)
                .y(100)
                .z(-500)
                .build()
            )
            .color(Color.GREEN)
            .preventRemoval(false)
            .hidden(false)
            .textStyle(WaypointTextStyle.builder()
                .showIcons(true)
                .labelScale(0.5F)
                .textIconScale(0.7F)
                .build())
            .build()
        );
    });
}

Showing or Hiding an Existing Waypoint

public void showWaypointExample(Player viewer) {
    Optional<ApolloPlayer> apolloPlayerOpt = Apollo.getPlayerManager().getPlayer(viewer.getUniqueId());
    apolloPlayerOpt.ifPresent(apolloPlayer -> this.waypointModule.showWaypoint(apolloPlayer, "KoTH"));
}

public void hideWaypointExample(Player viewer) {
    Optional<ApolloPlayer> apolloPlayerOpt = Apollo.getPlayerManager().getPlayer(viewer.getUniqueId());
    apolloPlayerOpt.ifPresent(apolloPlayer -> this.waypointModule.hideWaypoint(apolloPlayer, "KoTH"));
}
