Parsing rust cratename from toml, instead of filepath

[diajowe]

What this does

Panic-Analyzer pulls the crate name of the analyzed crate from the respective Cargo.toml file instead of pulling it out of the directory path

Why is this desired?

Since the crate name is not necessarily included in the filepath to a crate, it is safer to pull the crate name from the crate's Cargo.toml instead of the crate's file path

How is this achieved?

We are using the toml crate to parse toml files. To do so, the toml file is read into string (since the toml crate does not yet allow parsing of the toml from file directly). This should be ok since toml files are usually not gigabytes in size. The toml is then parsed for the "name" key under the "package" section.
