feat: implement fromReference method for HintReference

[tcoratger]

In order to transform a Reference instance into a HintReference instance:

• Reference structure
  

  ziggy-starkdust/src/vm/types/programjson.zig

  Lines 185 to 192 in 9cf73c8

  	pub const Reference = struct {
  	/// Tracking data for the register associated with the reference.
  	ap_tracking_data: ApTracking,
  	/// Program counter (pc) tied to the reference (optional, defaults to null).
  	pc: ?usize,
  	/// Value of the reference.
  	value: []const u8,
  	};

• HintReference structure
  

  ziggy-starkdust/src/hint_processor/hint_processor_def.zig

  Lines 13 to 61 in 9cf73c8

  	pub const HintReference = struct {
  	const Self = @This();
  	/// First offset value within the hint reference.
  	offset1: OffsetValue,
  	/// Second offset value within the hint reference.
  	offset2: ?OffsetValue,
  	/// Flag indicating dereference within the hint reference.
  	dereference: bool,
  	/// Ap tracking data associated with the hint reference (optional, defaults to null).
  	ap_tracking_data: ?ApTracking,
  	/// Cairo type information related to the hint reference (optional, defaults to null).
  	cairo_type: ?[]const u8,
  	/// Initializes a hint reference with specified offsets and dereference flags.
  	///
  	/// Params:
  	/// - `offset1`: First offset value.
  	/// - `offset2`: Second offset value.
  	/// - `inner_dereference`: Flag for inner dereference within the first offset value.
  	/// - `dereference`: Flag for dereference within the hint reference.
  	pub fn init(
  	offset1: i32,
  	offset2: i32,
  	inner_dereference: bool,
  	dereference: bool,
  	) Self {
  	return .{
  	.offset1 = .{ .reference = .{ .FP, offset1, inner_dereference } },
  	.offset2 = .{ .value = offset2 },
  	.dereference = dereference,
  	.ap_tracking_data = null,
  	.cairo_type = null,
  	};
  	}
  	/// Initializes a simple hint reference with the specified offset.
  	///
  	/// Params:
  	/// - `offset1`: First offset value for the hint reference.
  	pub fn initSimple(offset1: i32) Self {
  	return .{
  	.offset1 = .{ .reference = .{ .FP, offset1, false } },
  	.offset2 = .{ .value = 0 },
  	.dereference = true,
  	.ap_tracking_data = null,
  	.cairo_type = null,
  	};
  	}
  	};

we need a fromReference method similar to:
