Adjust the rendering of PNG and SVG formats for ACS style

Background Currently, the settings are not supported by rendering in PNG and SVG format.

Requirements

The following parameters should be processed for rendering: atomColoring - existing option render-coloring render-font-size render-font-size-unit render-font-size-sub render-font-size-sub-unit render-image-resolution (int number, default 72 ppi) bond-length-unit bond-length render-bond-thickness render-bond-thickness-unit render-output-sheet-width (default value: Letter format width = 11 inches) render-output-sheet-height (default value: Letter format height = 8.5 inches)
conversion from angstroms to units is done using bond-length. First calculate minimal bond length in angstrom b_ang (exclude zero bonds < eps=0.001) . Then take bond-length and bond-length-unit and calculate ang_to_in (angstorm to inch) conversion using minimal bond b_ang. Then calculate bond length in pixels using render-image-resolution e.g. if bond-length = 0.2 in, b_ang = 0.9A, then ang_to_in = 0.2/0.9 (in/A)= 0.22 in/A if render-image-resolution=600ppi, and bond is 1.5A then in pixels bond_length = 600 0.22 1.5 (px). And every object in angstroms (e.g. margin size) can be recalculated to pixels as object_size_A ang_to_in render-image-resolution
if render-output-sheet-width, render-output-wheet-height are specified then render should generate output image with specified height or width. The priority should be taken to width. E.g. if width and height both specified then take width (and calculate height according to bounding box of result structure). If width is not specified, then take height. If no properties were specified the calculate image size according to average bond length.

The new settings hashSpacingUnit hashSpacing imageResolution related issue: https://github.com/epam/ketcher/issues/5152 hashSpacingUnit values can be in cm/pt/px/in hashSpacing number with 1 decimal places the settings were moved to https://github.com/epam/Indigo/issues/2246

render-image-resolution can be high/low; PNG images should be able to be exported with the resolution of 600ppi (ACS standard preferred resolution/high resolution)> Current resolution (72ppi) is considered as low resolution. Regardless of the resolution, the size of the image should be such that one bond is ~0,5cm (0,2in/14,4pt) long when printed/100% zoom.

render-output-format-width render-output-format-hHeight are only for Indigo, Ketcher should not implement these parameters.
