feat: Greatly improved the IEEE754 tool (#1047)
I just realized one feature request existed about this tool and have
added a comment to it referring this pr. Errors and additions are
described in the fork commit already. I'm not sure if I should repeat
them here again. I have tested the changes thoroughly, but it is always
possible some fringe case was not tested and is incorrect. The tests
were done using the many similar online calculators for IEEE 754
floating point formats.
IEEE 745 floating point tool redesign modeled after 'float toy' web app
(http://evanw.github.io/float-toy/)

Streamlined output using colors and compact layout which can be further
simplified.
Chosen display mode (detailed or simplified) is automatically saved and
set on new sessions.
Edit the binary bits, the integer hexadecimal or the floating point
decimal values and the entire app will update with the change.
Supports the main IEEE745 standard formats (half, single and double
precision) together with custom formats of size <= 64 bits.
Each format choice uses and displays the number of significant decimal
digits defined by the mantissa size.
Added labels to identify the location of each bit box inside the binary
representation.
Satisfies round trip / idempotent (reproducing) conversion property
Added theme colors, radio buttons for display mode and a clear button
that resets the tool.
Removed previously and incorrectly added locale translation to various
labels and languages
Attempted to adhere to code style formatting using existing code as
example.
An effort was made to use preferred variable types and functions from
std namespace when appropriate.
Attempted to document code using comments. 

Not implemented / left to complete at an later time

Arbitrary width and precision formats. 
Extended precision formats.
Shortest string property.
hexadecimal floating point display and conversions.

// The decimal input is a bit more complicated. IEEE 754 floating point numbers are represented as a sign bit,
// an exponent and a mantissa. For details see https://en.wikipedia.org/wiki/IEEE_754.
// Workflow is as follows:
// From the bit checkboxes determine the integer hex value. This is straightforward.
// From the hex value determine the binary floating point value by extracting the sign, exponent and mantissa.
// From the binary floating point value determine the decimal floating point value using third party library.
// From the decimal floating point we reconstruct the binary floating point value using internal hardware.
// If format is non-standard the reconstruction is done using properties of the format.
