what's the difference between lv_label_set_text and lv_label_set_text_fmt?
lv_label_set_text makes the label like a string literal(aka we cant change it in runtime as it goes to the read-only memory part)
while the other is argument based string(aka we can change it dynamically/runtime)

what's the difference between lv_label_set_text and lv_label_set_text_fmt?
just did some trial and error
turns out
the "formatted" string wasn't the one i was thinking like itallic, bold etc...
it was related to passing variables similar to printf
