Matlab wrapper: typos in align.m

[izaakvc]

There were some errors in align.m, resulting in errors. It can be fixed by replacing the first 13 lines by this:

% Wraps librealsense2 align class
classdef align < realsense.processing_block
    methods
        % Constructor
        function this = align(align_to)
            narginchk(1, 1);
            validateattributes(align_to, {'realsense.stream', 'numeric'}, {'scalar', 'nonnegative', 'real', 'integer', '<=', realsense.stream.count});
            out = realsense.librealsense_mex('rs2::align', 'new', int64(align_to));
            this = this@realsense.processing_block(out);
        end
...

I believe this should be resolved in 2.16.5
