VHDL-Mode does not support grammar for statements: protected and protected body

VHDL-2002 and VHDL-2008 defined a thread-safe, object-oriented type called "protected" type. Please refer to the VHDL LRM.

An example source that has protected-type issues with Sublime Text, but compiles for test-bench just fine. The protected type can be defined in a package + package body, or in an architecture preamble. It provides a way to define a thread-safe type to aggregates data, procedure, and impure function into a single type definition. It is perhaps the most crucial data type for an advanced test-bench. (My opinion.)

Quoting from:

https://github.com/timothystotts/fpga-serial-acl-tester-1/blob/main/ACL-Tester-Design-Single-Clock-VHDL/Testbench/pmod_acl2.vhdl

In the package:

    -- A protected complex type to implement a 8-bit logic vector register
    -- with access to shared between multiple architecture processes. 
    type t_share_reg is protected
        impure function Get return std_logic_vector;
        procedure Set(constant c_reg    : in std_logic_vector(7 downto 0));
        procedure Update(constant c_bit :    std_logic; constant c_pos : natural range 0 to 7);
    end protected t_share_reg;

In the package body:

    type t_share_reg is protected body
        variable v_reg : std_logic_vector(7 downto 0) := (others => '0');

        impure function Get return std_logic_vector is
        begin
            return v_reg;
        end function Get;

        procedure Set(constant c_reg : in std_logic_vector(7 downto 0)) is
        begin
            v_reg := c_reg;
        end procedure Set;

        procedure Update(constant c_bit : std_logic; constant c_pos : natural range 0 to 7) is
        egin
            v_reg(c_pos) := c_bit;
        end procedure Update;
    end protected body t_share_reg;

I'd like to request if you could fix the syntax highlighting, as the indentation beautification, to support protected types.
