Instead of computing layout and then checking for overlaps, we can check for overlaps while computing layout.
also, fixed bug in auto header / footer height calculation causing overlapping error.
added 1px on both sides ( top/bottom ) of the table element.

moved computeRowElementDimensions & computeColumnLayout function calls inside computeRowLayout.

this is cleaner code and will be better design to allow recursive layout parsing.

- Current Logic for dynamic containers is not recursive.
    It loops through the elements and compute possible rows then it loops again and compute possible columns.

- This was less efficient, less flexible, and not recursive.
    Impact will be more apparent when we have multi pages and 100s to Elements.

- Now, I have added recursive logic to handle nested dynamic containers.
    current implementation have 2 functions computeRowLayout and computeColumnLayout.
    this functions that call each other to create a recursive layout until it's not possible.
    first, we compute main layout where we split it into 3 sections ( header, body, footer).
    then we run these functions on each of these sections and save the layout.

    In theory, we can set dynamicHeight for any element as long as it's not overlapping.

if rectangle is only ( basically no element is overlapping with it) or last element inside row or column, row and column layout is computed for children.
- if rectangle is overlapping with other element and we make it relative placement of other element will be broken so for now it is set to compute layout as per above condition

created patch that will convert isDynamicHeight Boolean to heightType with value "fixed" or "auto".

updated default objects and  control in Properties Panel.

changed schema version number to 1.2.0 as schema is changed and is incompatible with old formats (1.1.0)  we need to handle old formats.

updated jinja render template
- modified relative_containers to be recursive
- updated all templates to use heightType properties
- updated logic to include min-height
- added logic for backwards compatibility.
- also introduced dynamic height for static text if it has parseJinja enabled.
- updated rectangle template to be dynamic height

misc:
    is_older_schema now handles really old formats which don't have schema_version
    reverted styles for relative column

added logic to run patches on output print_formats that are used by jinja when required
