Update the lib with `@mtkmodel`

[ven-k]

This PR updates the lib with @mtkmodel DSL.

• The API remains same, except for ShiHeart; LV_V₀ is now LV.V₀ and all args follow the same pattern. As subcomponent args can be accessed with A.B syntax, this change is introduced.
• In tests, "Shi Model - Complex" is updated with a mtkmodel based circulatory system.
• Compliance, VariableCompliance, Elastance and ShiValve will be updated with a follow up PR. The first three need a way to set default values to conditional parameters and ShiValve needs a way to set continuous_events. PRs adding both are currently open upstream. Once they are merged I'll update them here.

The earlier syntax of extending components was @extend = var1, var2 = Component(). In a later version of MTK, that was changed to @extend Component(). This later version must have Julia compat as 1.9. So the CI has failed with 1.8.

Shall I update CI to 1.9, 1.10 (current latest) and nightly?

Also, the error on nightly is unrelated to this PR.

Thanks a lot for this. I had this on my todo list before Christmas, but put it on the back burner, because I did not know how to handle the conditionals. I will merge this PR now and once the other elements are adapted and MTK 9 has been tested with this (I hope to get to that in March), will release a new version.

Compliance, VariableCompliance, Elastance and ShiValve will be updated with a follow up PR. The first three need a way to set default values to conditional parameters and ShiValve needs a way to set continuous_events. PRs adding both are currently open upstream. Once they are merged I'll update them here.

I haven't followed upstream recently due to other commitments. Do we have these features (conditional parameters/branching, and continuous events) in the @mtkmodel framework?

[ven-k]

Yes; those features are now part of MTK@v9+.
