v0.2.0

Changes:

Note that all dates are in DD/MM/YYYY form.

04/17/2021

added legal copyright notations to the top of every source code file

improved API design:
- relocated read/write buffers in Maestro struct instead of localized buffers in each API
- all requests supported by Polulu Micro Maestro 6-Channel (i.e., set_target, get_position, etc.) implemented
- get requests (i.e., get_position, get_errors) return a u16 instead of a reference to the internal read buffer

finished documentation for all public modules and exports
formatted library using rustfmt (all formatting rules can be found in rustfmt.toml)
fixed implementation for raestro::constants::Errors
- when an error or errors are encountered, the Maestro returns a 2-byte (u16) integer in which each of the first 9 positions (i.e., bit 0 to bit 8) represent an error
- if the bit in position i (where i = 0..=8) is set, then the according error was thrown by the Maestro
- previous implementation of constants::Errors assumed that each error had a specific number attached to it (i.e., SER\_SIGNAL\_ERR was 0, SER\_BUFFER\_ERR was 1, etc.), which is incorrect

05/06/2021

the underlying uart instance was incorrectly configured to wait indefinitely if no bytes were read on the UART lines
this was updated so that Maestro::read would only block for 2 seconds, max (default configuration)
Maestro::set_target was updated to take in values in units of quarter-us, not us, since all other raestro APIs expect values in units of quarter-us
- docs were updated to reflect this change
