Subject: [PATCH] Add precompiled

Added an option for using precompiled libraries.

Empty if there is no precompilation.

```
compiler.libraries.ldflags=
```

Compiler Message when there is precompilation.

```
Compiling libraries...
Compiling library "aquestalk-esp32"
Library aquestalk-esp32 has been declared precompiled:
Using precompiled library in C:\Users\tanaka\Documents\Arduino\libraries\aquestalk-esp32\src\esp32
```

The precompiler cannot be used because it is not set up now.
