Error message needed to be revised
### Summary

Dear Developers, 

I think this line in file `dpgen/data/gen.py` should be revised for better description
```
680:         raise RuntimeError( "not file %s, vasp relaxation should be run before scale poscar" )
```
There is no value for string format.

### DP-GEN Version

devel

### Platform, Python Version, etc

_No response_

### Details

.
[BUG] not support formats otherwise POSCAR when using shuffle_poscar
### Bug summary
not support formats otherwise POSCAR when using shuffle_poscar

when running dpgen run, an error occured with "abacus/stru" format as sys_configs

```txt
nohup: ignoring input
INFO:dpgen:-------------------------iter.000000 task 03--------------------------
Traceback (most recent call last):
  File "/opt/mamba/bin/dpgen", line 8, in <module>

    cont = make_model_devi(ii, jdata, mdata)
  File "/opt/mamba/lib/python3.10/site-packages/dpgen/generator/run.py", line 1216, in make_model_devi

  File "/opt/mamba/lib/python3.10/site-packages/dpgen/generator/run.py", line 203, in poscar_shuffle
    numb_atoms = poscar_natoms(lines)
  File "/opt/mamba/lib/python3.10/site-packages/dpgen/generator/run.py", line 196, in poscar_natoms
    numb_atoms += int(ii)
ValueError: invalid literal for int() with base 10: 'LATTICE_CONSTANT'
```

I've checked the poscar_natoms func in dpgen/generator/run.py, and I think only a fixed POSCAR for vasp are supported
```python
def poscar_natoms(lines):
    numb_atoms = 0
    for ii in lines[6].split():
        numb_atoms += int(ii)
    return numb_atoms
```

when set ```"shuffle_poscar": false```, dpgen can run normally.

### DP-GEN Version

0.12.0

### Platform, Python Version, Remote Platform, etc

- Ubuntu 20.04 LTS (in Bohrium), 
- python: 3.10.6

### Input Files, Running Commands, Error Log, etc.

[run_param.json](https://github.com/user-attachments/files/15884351/run_param.json)


### Steps to Reproduce

running ```dpgen run run_param.json machine.json```

### Further Information, Files, and Links

_No response_
support fparam in lmp template

in previous version, if we use `template` in model deviation process, the generated LAMMPS input file would neglect fparam-dependence in DP model, as
```
pair_style      deepmd ../graph.000.pb ../graph.001.pb ../graph.002.pb ../graph.003.pb out_freq 10 out_file model_devi.out 
pair_coeff      * *
```



here we fixed this problem, as 
```
pair_style      deepmd ../graph.000.pb ../graph.001.pb ../graph.002.pb ../graph.003.pb out_freq 10 out_file model_devi.out fparam ${ELE_TEMP}
pair_coeff      * *

```

## Summary by CodeRabbit

- **New Features**
	- Enhanced the LAMMPS input model to support configurations based on electron temperature settings.
	- Added flexibility in handling different input scenarios with the introduction of a new parameter.

- **Bug Fixes**
	- Improved compatibility checks for the specified DeepMD version in the input model construction.

- **Documentation**
	- Updated comments for clarity regarding the new functionality and parameter usage.
