Completing extension strings...

This follows the same approach of gpufetch (in
6589de971750b7f4e52c0c35c031fe6204cefdba) where, instead of having a
separate struct for long and short names, both gets merged in a single
struct (ATTRIBUTE_INFO)

This indirectly fixes a bug in RISC-V printer where, if the output
was too large and the short name was selected, it could try to print
an out-of-bound value when accessing the ATTRIBUTE_PEAK. The reason is
that the long and short structures didnt have the same length (because
one attribute name was missing in the short struct). This is now fixed
since we have combined both long and short attribute names.

 ## 6. Bugs or improvements
+### 6.1 Unknown microarchitecture error
+If you get the `Unknown microarchitecture detected` error when running cpufetch, it might be caused by two possible reasons:
+
+1. You are running an old release of cpufetch (most likely)
+2. Your microarchitecture is not yet supported
+
+Download and compile the latest version (see https://github.com/Dr-Noob/cpufetch#22-building-from-source for instructions)
+and verify if the error persists.
+
+* __If the error dissapears__: It means that this is the first situation. In this case, just use the
+latest version of cpufetch which already has support for your hardware.
+* __If the error does not dissapear__: It means that this is the
+second situation. In this case, please create a new issue with the error message and the output of 'cpufetch --debug' on https://github.com/Dr-Noob/cpufetch/issues
+
+### 6.2 Other situations
