doc: adapt README to crates.io

bmap-rs and bmap-parser share the same README at this moment. This is
problematic because in crates.io once published bmap-parser contains
references to bmap-rs while if should be independent of it.

Fix the original README file.
Add a new README file for bmap-parser.

+## Installation
+```
+cargo install bmap-rs
+```
+
 ## Usage
 bmap-rs supports 1 subcommand:
 - "copy" - copy a file to another file using a bmap file.
 ```bash
-bmap-rs copy <SOURCE_PATH> <TARGET_PATH>
+bmap-rs copy <SOURCE_PATH>/<SOURCE_URL> <TARGET_PATH>
 ```
 
 The bmap file is automatically searched in the source directory. The recommendation is 
 to name it as the source but with bmap extension.
+If the file is remote, the bmap is also searched remotely.

+# bmap-parser
+
+The bmap-parser crate aims to implement tools related to bmap. The inspiration for it
+is an existing project that is written in python called [bmap-tools](https://salsa.debian.org/debian/bmap-tools).
+
+Right now, the implemented function is copying system images files using bmap, which is
+safer and faster than regular cp or dd. That can be used to flash images into block
+devices.
+
+## Usage
+```
+use bmap-parser::*;
+```
+There is a `copy` function that uses bmap file as reference, and a `copy_async` for the
+process to work in an asynchronous context.
