SlewRateLimiter unexpected behaviour

[JavierJJR]

Describe the bug 🐞

SlewRateLimiter arguments cannot be passed as parameters.

Expected behavior

SlewRateLimiter arguments can be passed as parameters or as numerical values, achieving the same result.

Minimal Reproducible Example 👇

The code below shows a toy example in which arguments are passed to the SlewRateLimiter as numerical values, which indeed works.

@mtkmodel sistemslew begin

	@components begin

		source = Step(start_time = 2, height = 1)
		limiter = SlewRateLimiter(y_start=0.0, rising = 1, falling = -0.5, Td = 0.001) 

	end

	@equations begin

		connect(source.output,limiter.input)

	end

end

@mtkbuild systemlim = sistemslew()

However, if arguments are passed as parameters, @mtkbuild fails:

@mtkmodel sistemslew begin
	
	@parameters begin

		limittest = 1

	end
	
	@components begin

		source = Step(start_time = 2, height = 1)
		limiter = SlewRateLimiter(y_start=0.0, rising = limittest, falling = -0.5, Td = 0.001) 

	end

	@equations begin

		connect(source.output,limiter.input)

	end

end

@mtkbuild systemlim = sistemslew()

Additional context

I wonder whether this is a bug or if there is something I am overlooking regarding the operation of this block.
