Added features

• Added to be able to set the left and right padding of the cell. You can set the left and right padding values with double defaultColumnTitlePadding and double defaultCellPadding in the configuration property.
• Added option to automatically enter edit state when selecting a cell. https://weblaze.dev/pluto_grid/build/web/#feature/editing-state
• Added keyboard move option with left and right arrow keys when reaching the left and right ends of text in edit state. (by PlutoGridConfiguration.enableMoveHorizontalInEditing)
• Added titleSpan property to custom text or icon in column title.
• Removed readOnly property of PlutoColumnType and added to PlutoColumn.
• Added checkReadOnly callback to dynamically manipulate readOnly property. https://weblaze.dev/pluto_grid/build/web/#add-and-remove-rows
• Added gridPopupBorderRadius property to round the corners of popups used inside the grid.

Note to users of previous versions

• Removed readOnly property of PlutoColumnType and added to PlutoColumn. The readOnly property has been changed from the existing PlutoColumnType to PlutoColumn, so if you are using the readOnly property in your existing code, you need to modify the code.
