[syncfusion_flutter_charts] Support specifying a maximum width for ColumnSeries

[btrautmann]

Use case

I would like to be able to constrain a ColumnSeries to never be wider than a certain width. In my use case, the user can constrain the data down to a small number of y values, e.g 1, at which point the ColumnSeries becomes very wide:

I'd prefer it if I could specify, say: maxWidth: 16 instead of only being able to play with the width parameter`, so that even if there is only one datapoint, it would look like this:

Is this maybe already possible?

Proposal

Add a maxWidth parameter:

ColumnSeries(
  maxWidth: 16, // New
  ...
),

One issue with this is that it would be confused with the width parameter which may conflict.
