[Bug] Negative signed integer in the input causes input parsing error

[queretareu]

🐛 Bug Report

When providing a negative signed integer as input in the input file, Leo fails to parse the input file and throws an error.

Steps to Reproduce

Run the following piece of code:

leo new hello
cd hello
cat <<EOF > src/main.leo
program hello.aleo {
 transition main(public a: i32, b: i32) {
      let c: i32 = a + b;
      assert(c == 0i32);
  }
}
EOF
cat << EOF > inputs/hello.in
[main]
public a: i32 = -1i32;
b: i32 = 1i32
EOF
leo execute

Code snippet to reproduce

Source code in src/main.leo:

program hello.aleo {
 transition main(public a: i32, b: i32) {
      let c: i32 = a + b;
      assert(c == 0i32);
  }
}

Input file in inputs/hello.in:

[main]
public a: i32 = -1i32;
b: i32 = 1i32

Stack trace & error message

       Leo ✅ Compiled 'main.leo' into Aleo instructions
Warning: Failed to parse input file

Error [ECLI0377018]: Failed to execute the `execute` command.
SnarkVM Error: 'hello.aleo/main' expects 2 inputs, but 0 were provided.

Expected Behavior

The input file should be parsed successfully and the program should execute without any errors.
