StoreFilter value_format_float_positional not working properly

[chaburkland]

Example

from io import StringIO
import static_frame as sf

raw = StringIO('count,score,color\n1,1.3,red\n3,5.2,green\n100,3,blue\n4,9.00,black')

sf.Frame.from_csv(raw, store_filter=sf.StoreFilter(value_format_float_positional="{:.2f}"))

The resulting frame is no different than if the store_filter was not provided

<Frame>
<Index> count   score     color <<U5>
<Index>
0       1       1.3       red
1       3       5.2       green
2       100     3.0       blue
3       4       9.0       black
<int64> <int64> <float64> <<U5>
