Support field width for floats

[Ockenfuss]

Hello everyone,

first of all, thank you for this awesome tool!
However, I am missing the possibility to specify the field width for floating point format specifiers, like e.g. %5f.
C's scanf functions support such a feature. From the scanf manpage on my system: "An optional decimal integer which specifies the maximum field width. Reading of characters stops either when this maximum is reached or when a nonmatching character is found, whichever happens first."

Unfortunately, I am not experienced enough with regular expressions to include this feature into scanf_translate myself. I opened a question on Stackoverflow concerning this feature. Any help is appreciated!

Thank you very much

Thanks for your interest! Unfortunately, I am also not enough of a regex master to know how to do the field width limiting. If anyone has a solution, PRs are certainly welcome!
