exchange groups of the byte reading macros with MBEDTLS_PUT_UINTxyz
and then shift the pointer afterwards. Easier to read as you can
see how big the data is that you are putting in, and in the case of
UINT32 AND UINT64 it saves some vertical space.

After removing config.h, the inclusion of it in common.h would be too late
in the code. Therefore common.h has been moved to where config.h used to
be included.

common.h already includes config.h, so a a file uses common.h
it no longer requires the definition/inclusion of config.h

minor changes, such as improving the documentation for the byte reading
macros, and using MBEDTLS_PUT_UINT16_xy in place of byte reading
macro combinations

Replace the contents of MBEDTLS_PUT_UINTx_yz contained inconsitent
but similar/duplicate code to the MBEDTLS_BYTE_x macros. Therefore
the contents of the macros now utilise the byte reading macros.
MBEDTLS_PUT_UINT64_LE's written order was also not consitent with
the other PUT macros, so that was modified.
Documentation comment said LSB instead of MSB and that has also been
resolved.

byte shifting opertations throughout library/ were only replaced with
the byte reading macros when an 0xff mask was being used.
The byte reading macros are now more widley used, however they have not
been used in all cases of a byte shift operation, as it detracted from
the immediate readability or otherwise did not seem appropriate.

Copy over the GET/PUT_UINT64_LE/BE macros from aes.c and sha512.c
Add the MBEDTLS_ prefix to all 4 macros.
Modify the GET_UINT64 macros to no longer take a target variable
as a parameter, so when the macro function is called it must be
assigned to a variable in the same statement.

The CHAR macros casted to an unsigned char which in this project
is garunteed to be 8 bits - the same as uint8_t (which BYTE casts
to) therefore, instances of CHAR have been swapped with BYTE and
the number of macros have been cut down

aria.c has a shift by 3 bytes, but does not use the 0xff masking.

These cast to an unsigned char rather than a uint8_t
like with MBEDTLS_BYTE_x
These save alot of space and will improve maintence by
replacing the appropriate code with MBEDTLS_CHAR_x

The GET macros used to write to a macro parameter, but now
they can be used to assign a value to the desired variable
rather than pass it in as an argument and have it modified
in the macro function.
Due to this MBEDTLS_BYTES_TO_U32_LE is the same as
MBEDTLS_GET_UINT32_LE and was there for replaced in the
appropriate files and removed from common.h
