ee5da4468d Fix interpolation/STRFMT overflow issues (#838)
Widths and fractional widths greater than 255 would overflow a
uint8_t and wrap around to smaller values.

Total formatted lengths greater than the avilable buffer size
would overflow it and potentially corrupt memory.

Fixes #830
Closes #831
