# Function to embed contents of a file as byte array in C/C++ header file(.h). The header file
# will contain a byte array and integer variable holding the size of the array.
# Parameters
# SOURCE_FILE - The path of source file whose contents will be embedded in the header file.
# VARIABLE_NAME - The name of the variable for the byte array. The string "_SIZE" will be append
# to this name and will be used a variable name for size variable.
# HEADER_FILE - The path of header file.
# APPEND - If specified appends to the header file instead of overwriting it
# NULL_TERMINATE - If specified a null byte(zero) will be append to the byte array. This will be
# useful if the source file is a text file and we want to use the file contents
# as string. But the size variable holds size of the byte array without this
